Truss quits as UK's Prime Minister

Truss bowed to the inevitable after her right-wing platform of tax cuts disintegrated and as many MPs among the ruling Conservatives revolted.

Speaking in Downing Street, Truss said she would stay on as prime minister until a successor is chosen to serve as Tory leader.

"We've agreed that there will be a leadership election to be completed within the next week," she said, after senior backbench MP Graham Brady told her the game was up.

"This will ensure that we remain on a path to deliver our fiscal plan and maintain our country's economic stability and national security.

"I will remain as prime minister until a successor has been chosen."

Labour leader Keir Starmer, whose opposition party has surged in opinion polls on the back of Truss's short, crisis-plagued tenure, demanded a general election "now".

The end for Truss came after a key minister resigned and many Tory MPs rebelled over an important vote in chaotic scenes at the House of Commons late Wednesday.

By Thursday morning, more than a dozen Conservative MPs had publicly urged Truss to resign, after her tax-cutting plans caused a market meltdown during an already severe cost-of-living crisis.

Many more were reported to have submitted letters to Brady calling for her to be removed, although party rules would have forbidden another leadership campaign for 12 months.

"The prime minister acknowledges yesterday was a difficult day and she recognises the public wanted to see the government focusing less on politics and more on delivering their priorities," her official spokesman told reporters.

Barely two hours later, she quit.

Events reached a head after what right-wing tabloid The Sun called "a day of extraordinary mayhem" on Wednesday.

Interior minister Suella Braverman left, apparently at Truss's demand after she sent a government document in a personal email.

But Braverman, an arch right-winger who enjoys strong support among the Tory membership, used her resignation message to attack Truss in blistering terms.
