Liz Truss's tenure as Prime Minister of the United Kingdom began on 6 September 2022 when she accepted an invitation from Queen Elizabeth II to form a government, succeeding Boris Johnson, and ended 49 days later on 25 October upon her resignation. As prime minister, she served simultaneously as First Lord of the Treasury, Minister for the Civil Service, and Minister for the Union.

Truss defeated Rishi Sunak in the July–September 2022 Conservative Party leadership election on 5 September and was appointed prime minister the following day. Elizabeth II's death on 8 September caused government business to be suspended during a national mourning period of 10 days. In response to the cost-of-living crisis and energy supply crisis, the Truss ministry announced the Energy Price Guarantee, which reduced energy prices for households, businesses, and public sector organisations. Kwasi Kwarteng, then Chancellor of the Exchequer, announced large-scale borrowing and tax cuts in a mini-budget on 23 September. The mini-budget was widely criticised and largely reversed, having led to financial instability.

Truss dismissed Kwarteng without explanation on 14 October and appointed Jeremy Hunt to succeed him. Suella Braverman resigned as Home Secretary on 19 October after admitting to having used her personal email address to send a Cabinet document. Her resignation letter was critical of Truss's government. On the evening of 19 October, MPs voted to reject a motion which would guarantee parliamentary time for a bill to ban fracking in the UK. The vote was controversial as it was unclear whether a three-line-whip had been issued to Conservative MPs, ordering them to vote against it. Allegations of "manhandling" and intimidation were made by a number of MPs against some government ministers. Following these events, together with mounting criticism and loss of confidence in her leadership, Truss announced on 20 October her intention to resign as party leader and as prime minister. Sunak was elected unopposed as her successor and succeeded her as leader on 24 October and as prime minister on 25 October.^[1][2][3]

Truss is the third female prime minister, following Margaret Thatcher and Theresa May, and is both the last of 15 UK prime ministers to have served under Elizabeth II and the first to have served under King Charles III. She is the shortest-serving prime minister in the country's history, and recorded the lowest approval ratings of any UK prime minister.^[4][5][a]
