LONDON (AP) — British Prime Minister Liz Truss has resigned — bowing to the inevitable after a tumultuous six-week term in which her policies triggered turmoil in financial markets and a rebellion in her party obliterated her authority.

She said “I cannot deliver the mandate on which I was elected.”

Just a day earlier Truss had vowed to stay in power, saying she was “a fighter and not a quitter.”

But Truss left Thursday after she was forced to abandon many of her economic policies and lost control of Conservative Party discipline.

Her departure leaves a divided party seeking a leader who can unify its warring factions.

Truss held on to power by a thread Thursday, after a senior minister quit her government with a barrage of criticism and a vote in the House of Commons descended into chaos and acrimony.

Truss was due to make statement amid intense speculation about her future. The event at Downing Street comes after Truss held a hastily arranged meeting with a Conservative official tasked with assessing whether the prime minister still has the support of Tory members of Parliament.

A growing number of lawmakers have called for Truss to resign after weeks of turmoil sparked by her economic plan. The plan unveiled by the government last month triggered financial turmoil and a political crisis that has seen the replacement of Truss’ Treasury chief, multiple policy U-turns and a breakdown of discipline in the governing Conservative Party.

Many Conservatives say Truss must resign – but she remained defiant Wednesday, saying she was “a fighter and not a quitter.”
