Liz Truss has officially resigned as British Prime Minister after being in office for 45 days.

This is the shortest tenure of any UK prime minister.

BBC reported that the second shortest-serving PM was George Canning, who served for 119 days after dying in 1827.

Events leading to Liz Truss’s resignation

Trouble began when Truss’s first Chancellor, Kwasi Kwarteng, spooked the financial markets with his mini-budget on September 23.

Most of those policies were reversed three weeks later by the second finance minister, Jeremy Hunt.

Since then, Conservative disquiet has morphed into widespread anger within the parliamentary party.

Her stepping down on Thursday, October 20, follows dramatic scenes in the House of Commons last night over a vote on fracking.

Calls for her to go kept growing in the hours afterwards. But during her address outside Downing Street, Truss argued that she came into office at a time of “great economic and international instability”.

Key issues at hand

While announcing her resignation, Truss said she could not deliver the mandate on which she was elected as Tory leader and had notified the King that she was resigning.

She says her government delivered on energy bills and cutting national insurance and had a vision for a “low tax high growth economy”.

“I recognise… given the situation, I cannot deliver the mandate on which I was elected by the Conservative Party,” she explained.

Truss’s premiership has been in turmoil since her mini-budget last month, which rocked markets and was later scrapped by her new chancellor.

The resignation of her home secretary on Wednesday and a chaotic vote in the Commons sealed her fate.

Who could replace Liz Truss? – Rishi Sunak

A new YouGov poll on Tuesday, October 18, found Rishi Sunak has the best ratings of the touted alternatives to Truss — albeit still with an overall net favourability rating of -18.

But he is also now viewed as a divisive figure.

Many party members, who get the final say on who leads the party, are unwilling to forgive him for his role in ousting ex-prime minister Boris Johnson.
