Draft:2022 Conservative Party leadership formation

The July–September 2022 Conservative Party leadership election was triggered by Boris Johnson's announcement on 7 July 2022 that he would resign as Leader of the Conservative Party and Prime Minister of the United Kingdom, following a series of political controversies. In the 2019 Conservative Party leadership election, Johnson was elected to succeed Theresa May after she had been unable to secure a majority for her Brexit withdrawal agreement. After having lost his working majority to defections and his own suspensions of rebel Members of Parliament, Johnson called a general election on a platform of completing the UK's withdrawal from the European Union. In that general election, the Conservative Party won their biggest majority in Parliament since 1987, and Johnson was able to pass a revised version of May's withdrawal agreement.

In response to the COVID-19 pandemic in the UK, Johnson and his government had instituted public health restrictions, including limitations on social interaction, that Johnson and some of his staff were later found to have broken. The resulting political scandal (Partygate), one of many in a string of controversies that characterised Johnson's premiership, severely damaged his personal reputation. Johnson won a confidence vote by Conservative MPs in June 2022. The situation escalated with the Chris Pincher scandal in July 2022, and between 5 and 7 July, more than 60 government ministers, parliamentary private secretaries, trade envoys, and party vice-chairmen resigned in what was the largest mass resignation in British history. Many previously supportive MPs called for Johnson to resign. This brought about a government crisis, culminating on 7 July, when Johnson announced that he would resign as party leader. Johnson also announced that he would remain as prime minister until a successor was elected.

Voting took place between 13 July and 2 September. After a series of MP ballots, the list of candidates was narrowed down to Liz Truss, who served as Foreign Secretary and Minister for Women and Equalities under Johnson's leadership, and Rishi Sunak, who served as Chancellor of the Exchequer until 5 July. On 5 September, Truss was elected to lead the party, and assumed the premiership on 6 September. In her victory speech, Truss thanked Johnson and stated that her new government would cut taxes and deal with the energy crisis. Truss would later resign after 50 days in office amid an economic and political crisis, which made her the shortest-serving prime minister in British history. Truss would be succeeded by Sunak, after he won the leadership contest to replace her.
