Records of members of parliament of the United Kingdom

This article about records of members of parliament of the United Kingdom and of England includes a variety of lists of MPs by age, period and other circumstances of service, familiar sets, ethnic or religious minorities, physical attributes, and circumstances of their deaths.

Youngest
Prior to the Acts of Union, the youngest known person to have sat in the House of Commons of England was Christopher Monck, elected MP for Devon in 1667, "probably without a contest", at the age of 13. He sat in the House for three years, before being elevated to the House of Lords upon his father's death. He is said to have been "moderately active during his short period of membership, sitting on seven committees".

Monck was one of many members returned underage in the late seventeenth century, with around ten underage members in each of the Parliaments of 1690 and 1695, many aristocrats. In response to this, the Parliamentary Elections Act 1695 established 21 as the minimum age, although this was not reliably enforced. Until the Reform Act 1832, underage MPs were seldom unseated. For example, Charles James Fox became an MP aged 19 in 1768, and Robert Jocelyn, Viscount Jocelyn, became an MP aged 18 in 1806.

Before the general election of 2015, the youngest MP since the Reform Act of 1832 was William Charles Wentworth-FitzWilliam, elected at Malton in the 1832 general election aged 20 and 11 months. His election, whilst theoretically illegal, was unchallenged; Malton was a pocket borough controlled by his family, and the matter was viewed as academic as he would be of full age by the time Parliament assembled.

After Wentworth-FitzWilliam, the youngest MP elected was James Dickson, who was elected as a Liberal at a by-election for the Borough of Dungannon on 25 June 1880. He was born on 19 April 1859, and so was aged 21 years 67 days. The youngest female MP was Bernadette Devlin, elected on 17 April 1969 from Mid Ulster, aged 21 years 359 days. Until 1970, the minimum age to sit in parliament was 21. In 1970, the minimum age was lowered to 18. Both records are now jointly held by Mhairi Black, who was aged 20 years and 237 days old at the time of her election to the seat of Paisley and Renfrewshire South in the 2015 general election.

Oldest
The oldest serving MP whose exact dates are known was Samuel Young (1822–1918), who was MP for East Cavan from 1892 (when aged 70), until his death at the age of 96 years 63 days.

Oldest debuts
Perhaps the oldest parliamentary debut of all time was that of Warren Lisle, believed born in 1695, who was elected on 7 September 1780 during that year's general election as MP for Weymouth and Melcombe Regis as locum tenens, aged reportedly 85. He stood down on 21 November to allow his kinsman, Gabriel Steward, to stand for the seat after completing his own term as mayor of the borough (when he had been the local returning officer). He died in July 1788 aged reportedly 93.

The oldest debut where a confirmed birth date is known was made by Sir Robert Pullar (born 18 February 1828) who was elected at an unopposed by-election for Perth on 12 February 1907 aged 78 years and 359 days. He retired at the January 1910 general election.

The oldest debut at a general election to the UK Parliament was possibly by Bernard Kelly (born 1808) who was elected MP for South Donegal in 1885 in the year of his 77th birthday. He died in office on 1 January 1887 aged 78.

The oldest woman at first entry to the Commons was Dr Ethel Bentham (born 5 January 1861) who was elected MP for Islington East at the 1929 general election aged 68 years and 145 days. She died in office, the first woman to do so, in 1931.

Jim Allister was the oldest MP first elected at the last general election, the 2024 general election, at age 71.

David Hacking was the oldest hereditary peer elected to the House of Lords in a by-election, aged 83 in 2021. He had previously been in the House for 28 years before leaving in 1999.

Longest-lived MP
Although his alleged birth year predates parish registers and civil birth registration, William Badger, who was member for Winchester in the 1597 parliament of England, is supported by a History of Parliament biographer to have been a centenarian, being established to have been born 'circa 1523' and to have been buried on 18 January 1629, aged at least 105 years.

Ronald Atkins (13 June 1916 – 30 December 2020), member for Preston North from 1966 to 1970, and again from 1974 to 1979, was the longest-lived former MP whose birth date is registered. His daughter Charlotte Atkins also served as an MP from 1997 to 2010. On 30 August 2018, he surpassed the previous record set by Theodore Cooke Taylor (3 August 1850 – 19 October 1952), member for Radcliffe-cum-Farnworth from 1900 to 1918, who had lived to be 102 years and 77 days old. Atkins died aged 104 years and 200 days old.

Other ex-MPs who have reached their centenary are Nathaniel Micklem (1853–1954), Sir Harry Brittain (1873–1974), Sir George Ernest Schuster (1881–1982), Manny Shinwell (1884–1986), Edgar Granville (1898–1998), Jack Oldfield (1899–1999, who outlived his parliamentary service by 68 years), Hartley Shawcross (1902–2003), Bert Hazell (1907–2009), Michael Shaw (1920–2021) and Sir Patrick Duffy (born 1920, and the only centenarian former MP currently living).

Frank James, who was elected MP for Walsall at the 1892 general election, but unseated on petition in November that year, died at 102 years and 135 days old; James's record was surpassed by Atkins on 27 October 2018.

, Sir Patrick Duffy is the oldest living former MP (born 17 June 1920, age 104 years, 38 days).

Jill Knight (9 July 1923 – 6 April 2022) was the longest-lived female former MP, aged 98 years, 271 days.

Elizabeth Shields is the oldest living female former MP (born 27 February 1928, age 96 years, 146 days).

Stratton Mills (born 1 July 1932, age 92 years, 21 days), who was elected MP for Belfast North at the 1959 general election, is the earliest elected former MP still living. Mills was sworn in on 22 October.

Shortest-lived MPs
One known contender for this record for whom both birth and death dates are known, in the Parliament of England, was James Wriothesley, Lord Wriothesley, who while still a minor was MP for Callington in 1621–1622, and for Winchester from early in 1624 until his death from illness on military service in the Netherlands on 1 November 1624 aged 19 years and 251 days.

Based only on evidence from his university entrance records, Peter Legh, MP for Newton from 1640, may have been aged 19 or younger when he died after a duel on 2 February 1642, but his precise birthdate is not known.

Geoffrey Palmer, MP for Ludgershall from March 1660, died in office on 31 October 1661 aged 19 years and at least 245 days, based on his baptism registration (28 February 1642).

After the setting of the youngest age of candidacy at 21, the youngest MP to die in office was George Charles Grey who was elected MP for Berwick-upon-Tweed in 1941 and was killed in action on 30 July 1944 aged 25 years 240 days. Throughout this period he was the Baby of the House.

The shortest-lived female MP, Lady Cynthia Mosley, MP for Stoke 1929–1931, died in 1933 aged 34. The youngest female MP to die in office was Jo Cox, MP for Batley and Spen since 2015, who was murdered on 16 June 2016, 6 days before her 42nd birthday.

Longest
Sir Francis Knollys (also the oldest ever sitting MP) was first elected as MP for Oxford in 1575 at the age of around 25 and was MP for Reading at the time of his death in 1648, a period spanning 73 years, although there were eight periods, amounting to 27 entire years (1590–1592, 1594–1596, 1599–1600, 1602–1603, 1605–1613, 1615–1619, 1627 and 1630–1639) in which the Parliament of England did not meet, and his period of service totalled little more than 23 years.

The longest span of service of an MP since the start of the 20th century was Winston Churchill who was first elected on 1 October 1900 and left the House of Commons on 25 September 1964, a period of 63 years 360 days. His service was not continuous, as he was not an MP for a spell in 1908 and between 1922 and 1924.

Charles Pelham Villiers was the longest continuously serving MP. He was elected in 1835 and remained an MP continuously for over 62 years until his death on 16 January 1898, aged 96 years 13 days. Since the start of the 20th century, the longest continuous service by an MP has been 51 years 80 days by Edward Heath, who sat from 1950 to 2001.

The longest continuous service record for a female MP is held by Harriet Harman, first elected in October 1982. The longest total service record for a female MP is held by Dame Margaret Beckett, who served for 4 years and 7 months between 1974 and 1979 and was then re-elected in June 1983. Beckett also holds the record for the longest span of service for a woman. Both Harman and Beckett left the House of Commons on 30 May 2024.

Shortest
There are cases of MPs being elected posthumously; Edward Legge (1710–1747) was elected unopposed as MP for Portsmouth on 15 December 1747, four days before news arrived that he had died 87 days previously in the West Indies. In 1780 John Kirkman was elected as MP for the City of London despite dying before polls closed.

In more recent times, members have died after polling, but before the declaration of the results. In 1906, Thomas Higgins was declared elected for the seat of North Galway, even though he had died earlier that morning, after polling day. More recently, in 1945 Sir Edward Taswell Campbell at Bromley and Leslie Pym at Monmouth died after polling, but nine days before the declaration of the results. Both were declared elected posthumously, and both had been MPs for a number of years. Noel Skelton is another example in 1935.

The shortest non-posthumous service was that of Alfred Dobbs, who was declared elected MP for Smethwick on 26 July 1945 and was killed the following day in a car accident on the way to take his seat.

The shortest service for women MPs has been 92 days in the case of both Ruth Dalton, who was MP for Bishop Auckland from a by-election on 7 February 1929 to dissolution of Parliament on 10 May 1929 prior to that year's general election, and Margo MacDonald, who was MP for Glasgow Govan from a by-election on 8 November 1973 until the dissolution of Parliament on 8 February 1974 prior to the coming general election.

However, none of them took their seat in the House of Commons, instead attending the First Dáil.

MPs who have sat for three or more different constituencies

MPs who have made more than one comeback
In modern times, it is unusual for an MP who has been defeated (or retired e.g. due to their seat being abolished) to achieve more than one comeback to the House of Commons after a period of absence. In the UK Parliament, William Vesey-FitzGerald, Lord Charles Beresford and Arthur Henderson were exceptional in achieving it on no fewer than four occasions each: Vesey-FitzGerald over a span of 18 years through three by-elections and one general election, Beresford over a span of 25 years after voluntarily resigning or retiring from the House at stages of his naval career, Henderson invariably at by-elections following serial general election defeats in other seats, in the shorter span of 14 years. A woman has never come back more than once.

Of living MPs, George Galloway transferred to a different constituency and party in 2005 but did not have any period of absence from the Commons at that time. Having left Parliament in 2010 he made a comeback at a by-election in a third constituency in 2012, was defeated in 2015, then returned at a by-election for a fourth constituency in February 2024 before losing it in the general election the same year.

Longest delay before making a comeback
In absolute terms two 17th-century members of the English Parliament had 35-year intervals outside the House of Commons:


 * Edward Mainwaring, 35 years and 269 days from serving as MP for Newcastle-under-Lyme in the parliament that closed on 12 August 1625, to returning for the same seat at start of the Cavalier Parliament on 8 May 1661,
 * Sir William Killigrew who was out of the Commons 35 years and 30 days from the close of the 1628 parliament on 10 March 1629 when he served as MP for Penryn, Cornwall, until returning as MP for Richmond, Yorkshire on 9 April 1664

Note that intervals of more than a decade between service in the Commons were more commonplace in the 17th than in later centuries due to factors such as:
 * -years when no parliaments were held, such as Charles I's rule without parliament covering 1630–39,
 * -Royalist MPs expelled during the English Civil Wars sitting again after the restoration of Charles II (1660),
 * -the Cavalier Parliament of 1661–79 which met without general elections in meantime.
 * -former Civil War and Commonwealth era Roundhead MPs returning to the Commons in the 1670s and 1680s under the Whig Party.

Since the establishment of regular parliamentary government at the end of the 17th century and the creation of the United Kingdom Parliament in 1801, possibly the longest gap between sitting was faced by Henry Drummond (1786–1860), of nearly 35 years between the dissolution of his first parliament on 29 September 1812 and returning to his next at the general election held in July–August 1847.

Mother-daughter sets of MPs
These are rarer than father-son sets:


 * Edith Summerskill, MP for Fulham West 1938–1955 and Warrington 1955–1961, was mother of Shirley Summerskill, MP for Halifax 1964–1983. Their consecutive service in the Commons totalled 43 years and spans 45 years.

The first sister set to succeed each other, indirectly, to the same constituency have been Jo Cox and Kim Leadbeater who both represented Batley and Spen respectively in 2015-2016 and since by-election in 2021.

Constituency representation
Most women representing:

Halifax (in 1964–83 and since 1987) has, since 2024 – been represented by a fifth woman to sit for the constituency.

Longest period represented by women MPs:

Birmingham Edgbaston has been represented by 4 women MPs in continuous succession since a by-election on 2 July 1953, a period of 70 years, apart from a vacancy interval of 63 days between the death of Dame Edith Pitt on 27 January 1966 and the election of her successor Dame Jill Knight at the general election that year.

Husband-wife sets of MPs
First couples to serve as MPs


 * Indirectly successively – John Stewart-Murray, Marquess of Tullibardine was MP for West Perthshire from the December 1910 general election until 1917 when he succeeded his father as Duke of Atholl and moved to the House of Lords. His wife Katharine Stewart-Murray, Duchess of Atholl, was MP for Kinross and West Perthshire from 1923 to 1938.
 * Directly successively – Waldorf Astor (later 2nd Viscount Astor), who was MP for Plymouth December 1910 – December 1918 and Plymouth Sutton December 1918 – October 1919 (on succession to hereditary peerage), and Nancy Astor, Viscountess Astor, who succeeded him as MP for the latter seat, becoming the first woman to take her seat in the Commons, from by-election in November 1919 until July 1945.
 * Concurrently – Walter Runciman, MP for Swansea West 1924–1929 and Hilda Runciman, MP for St Ives 1928–1929. She relinquished the latter seat at the 1929 general election, enabling him to hold the seat until 1937. (He was also, previously, MP for Oldham 1899–1900 and Dewsbury 1902–1918.)

First widow elected to succeed deceased husband as MP

Margaret Wintringham who became MP for Louth, Lincolnshire in 1921 at by-election following death of her husband Thomas Wintringham, who had only served since June 1920 and had died in August 1921. She lost the seat at the 1924 general election. She was the second woman to take her seat in the Commons.

Longest concurrent Commons service as married couple

Nicholas Winterton and Ann Winterton – 27 years, from the latter's election in 1983 for Congleton until both retired at the 2010 general election. The former had commenced serving as MP for Macclesfield from 1971. They are also contenders for the record of couple with highest collective years of service in the Commons, totaling 66 years.

Longest span of couple's service in the Commons


 * (Consecutive) – Noel Buxton, MP for Whitby from by-election in May 1905 to 1906, and for Norfolk North 1910 to 1918 and 1922 to 1930 when he was raised to peerage as Baron Noel-Buxton, following which his wife Lucy, Baroness Noel-Buxton served as MP for Norfolk North from 1930 to the 1931 general election, and for Norwich from 1945 to 1950, making a span of nearly 45 years.
 * (Concurrent) – Aneurin Bevan was MP for Ebbw Vale from 1929 (until his death in 1960), while his wife Jennie Lee, served from 1945 to 1970 as MP for Cannock, making a span of 41 years and 18 days. The latter had been MP for North Lanarkshire from 1929 to 1931, prior to their marriage in 1934.

Although differing in that the husband's service preceded and outlasted the wife's, the Bevans' span has been surpassed by Sir Peter Bottomley who served in the Commons from 26 June 1975 to the 2024 general election, and his wife Virginia, who sat as MP for South West Surrey from by-election on 4 May 1984 to the 2005 general election – a period of 48 years, 351 days.

Representation of a constituency by a couple

The establishment of single-member seats by the 20th century as the norm for parliamentary constituencies means there have been no concurrent representations of a constituency by a couple but successive representations by one spouse after the other has died or relinquished the seat have been relatively commonplace in parliament.

Hemel Hempstead was represented the longest, for nearly 39 years, by John Davidson from a by-election in November 1920 until he was elevated to the House of Lords as Viscount Davidson in 1937, when the seat was represented by his wife Frances Davidson, Viscountess Davidson from the subsequent by-election until her retirement at the October 1959 general election.

Louth, Lincolnshire was represented for the shortest time, a total of 4 years and 3 months, by Thomas Wintringham from June 1920 to his death in August 1921, then by his widow, Margaret, from the by-election in September 1921 to the general election in October 1924.

Couples who served separately as MPs before marriage but not together after


 * Campbell Stephen, MP for Glasgow Camlachie 1922–1931 and 1935 to his death in 1947, who married in 1945 Dorothy Jewson, who had been MP for Norwich in 1923–1924.

Largest set
Six brother sets:


 * Francis Seymour-Conway, Viscount Beauchamp (later 2nd Marquess of Hertford) served 1766–1794; Lord George Seymour-Conway 1784–1790 and 1796–1801; Henry-Seymour-Conway (later Lord Henry Seymour) 1766–1784; Lord Robert Seymour 1771–1790 and 1794–1820; Lord William Seymour 1783–1784 and 1785–1796; and Lord Hugh Seymour 1784–1786 and 1788 to his death in 1801. All began serving in the pre-1801 Parliament of Great Britain and their service in the Commons totalled 126 years.
 * Henry Paget, Lord Paget (later 1st Marquess of Anglesey) served 1790–1804 and 1806–1810; Arthur Paget 1794–1807; Berkeley Paget 1807–1826; Sir Charles Paget 1804–1826 and 1831–1833 and 1833–1834; Sir Edward Paget, 1796–1806 and 1810–1820; and William Paget 1790 to his death in 1794. Four of the brothers began serving under the pre-1801 Parliament of Great Britain and their service in the Commons totalled 79 years.

Longest span of service in the Commons by brothers
Probably the longest (though not continuous) all time span of service by brothers in the Commons, in the Parliament of England, was 85 years from 1562, when Sir Henry Knollys was elected MP for Reading, until the death in 1648 of his brother Sir Francis Knollys (above, aged reputedly 97) also representing Reading, although there were intervals of years when parliament did not meet. They were part of another set of six brothers who all sat at various times.

Since regular parliamentary government was established by the start of the UK Parliament, contenders for longest span of continuous service include the four brothers Sir Robert Peel (also twice prime minister), William Yates Peel, Jonathan Peel and Edmund Peel, with a span of 59 years from Robert's by-election return on 15 April 1809 as MP for Cashel, to the retirement of Jonathan at the 1868 general election as MP for Huntingdon. Their collective service totalled 115 years and all four were simultaneously in Parliament when Edmund was sitting in 1831–1832 and 1835–1837 for Newcastle-under-Lyme. Another 59-year service span was enjoyed by two brothers, William Lowther, 2nd Earl of Lonsdale (when Viscount Lowther before entering the House of Lords in 1841) and Henry Cecil Lowther, from the former's election as MP for Cockermouth in 1808 until the death of the latter as MP for Westmorland (which he had represented since 1812) and Father of the House on 4 December 1867.

Thomas Hyde Villiers and his brother Charles Pelham Villiers (above) had a span of nearly 72 years service from the former's first election as MP in 1826 to the latter's death as a serving MP and Father of the House in 1898, but this was broken by an interval when the former was out of parliament in 1831, and the gap between Thomas' death on 3 December 1832 and Charles' first election in 1835. Their consecutive service thus totalled 69 years.

Representation of same constituency by brothers
Where seats were in the patronage of territorial magnates, it was commonplace into the 19th century for brothers in (usually landowning) families to hold seats successively or (before the advent of single member seats) even concurrently, before the system of choosing candidates by local party associations became organised on a competitive selection basis. Two brothers successively represented North Derbyshire for a total span of nearly 48 years. Lord Cavendish of Keighley was MP from the 1832 general election until succeeding his father and going to the House of Lords as Earl of Burlington in 1834. He was succeeded by Lord George Henry Cavendish from 1834 until the latter's death on 23 September 1880.

The last set of brothers to represent the same constituency were Frederick and Henry Guest, who did so in connection with two successive constituencies:
 * East Dorset. Frederick was first elected at the January 1910 general election but was unable to take his seat due to irregularity by an election agent, causing a by-election in June 1910 when he stepped aside in favour of Henry, who held the seat until the December 1910 general election when Henry in turn stepped aside in favour of Frederick who was elected, to hold the seat until the 1922 general election.
 * Plymouth Drake, of which Frederick was MP from 1931 to his death in 1937 when Henry succeeded him at the by-election and held the seat until the 1945 general election.

 * Victor Cazalet, MP for Chippenham 1924–1943 and his sister Thelma Cazalet-Keir, MP for Islington East 1931–1945.

Twins
James Grenville and Richard Grenville sat together as MPs for Buckingham from 1774 to 1780.

Edward John Stanley, MP for North Cheshire, sat alongside his brother William Owen Stanley, MP for Anglesey, from 1837 to 1841.

Angela Eagle and Maria Eagle, mentioned above, are the only twin sisters to have sat in the Commons together, last elected in 2019.

First general election victors by religious affiliation
When the UK Parliament was established in 1801, non-Anglicans were prevented from taking their seats as MPs under the Test Act 1672. However, Methodists took communion at Anglican churches until 1795, and some continued to do so, and many Presbyterians were prepared to accept Anglican communion, thus ensuring that members of these creeds were represented in the Parliament. Some Unitarians were also elected.

The first Roman Catholic general election victors in the UK Parliament were at the 1830 general election. They included Daniel O'Connell and James Patrick Mahon in Clare.

The first Quaker general election victor was Joseph Pease at the 1832 general election.

The first Moravian general election victor was Charles Hindley at the 1835 general election.

The first Jewish general election victor was Lionel de Rothschild at the 1847 general election. He was not permitted to take his seat until 1858.

The first Catholic Apostolic general election victor was Henry Drummond also at the 1847 election.

The first Baptist general election victor was George Goodman at the 1852 general election.

The first Congregationalist general election victor was Samuel Morley at the 1865 general election.

The first declared atheist general election victor was Charles Bradlaugh at the 1880 general election. He was not permitted to take the oath until January 1886, although he sat briefly in 1880–81 when permitted to affirm allegiance; a legal action later held that affirmation had no effect.

The tallest MP of all time is believed to be Daniel Kawczynski, MP for Shrewsbury and Atcham between 2005 and 2024, at 6 ft in 2007, later stated to be 6 ft in 2014.

The tallest female MP of all time is believed to be Antoinette Sandbach at 6 ft in 2011, when she was a Senedd Cymru – Welsh Parliament (formerly National Assembly for Wales) member, later stated to be 6 ft in 2019. She served in the House of Commons as MP for Eddisbury in 2015–2019.

Members of Parliament who have died by suicide
The Irish republican Bobby Sands died while on hunger strike in May 1981; he had been elected as an "Anti-H-Block" MP for Fermanagh and South Tyrone in April 1981, although he never took his seat as he was in prison. Although hunger strike deaths are arguably self-inflicted, they are not conventually considered "suicides."
