Miles Lampson, 1st Baron Killearn

Miles Wedderburn Lampson, 1st Baron Killearn, (24 August 1880 – 18 September 1964) was a British diplomat.

Background and education
Miles Lampson was the son of Norman Lampson, and grandson of Sir Curtis Lampson, 1st Baronet. His mother was Helen, daughter of Peter Blackburn, MP for Stirlingshire. He was educated at Eton.

Diplomatic career
Lampson entered the Foreign Office in 1903. He served as Secretary to Garter Mission, Japan, in 1906, as 2nd Secretary at Tokyo, Japan, between 1908 and 1910, as 2nd Secretary at Sofia, Bulgaria in 1911, as 1st Secretary at Peking in 1916, as Acting British High Commissioner in Siberia in 1920 and as British Minister to China between 1926 and 1933.

In 1934 he was appointed High Commissioner for Egypt and the Sudan. As a result of the Anglo-Egyptian Treaty in December 1936, to which Lampson was a signatory, Britain loosened its grip on Egypt and the post title was changed to Ambassador to Egypt and High Commissioner for the Sudan in 1936. Lampson continued in this office until 1946. As ambassador to Egypt he forced King Farouk I to change the cabinet to a Wafdist one through surrounding the king's palace with tanks in the Abdeen Palace incident of 1942.

He was then Special Commissioner in Southeast Asia between 1946 and 1948. He was admitted to the Privy Council in 1941 and raised to the peerage as Baron Killearn, of Killearn in the County of Stirling, on 17 May 1943. He was also awarded the Order of the Rising Sun, Gold Rays with Neck Ribbon of Japan and the Order of the Sacred Treasure, Gold Rays with Neck Ribbon of Japan.

Succession
