LONDON: British Prime Minister Liz Truss on Thursday resigned as the Conservative Party leader expressing that she can no longer deliver the mandate she was elected on last month, ending her humiliating tenure at 10 Downing Street on her 45th day in the job after an open revolt against her chaotic leadership.

The  outgoing prime minister will stay in charge until her successor is elected by the governing Tory party, with a speeded up leadership election to be completed by next week. Her former leadership rival, Rishi Sunak, is seen as a possible frontrunner in that race but a consensus within a divided Tory party remains elusive, with the Opposition Labour Party renewing calls for an immediate general election.

Meanwhile, the ousted premier Boris Johnson is said to be considering another go in a race that is unlikely to have a clear choice, with former contenders Penny Mordaunt and Suella Braverman and UK Defence Secretary Ben Wallace among the names circulating. "I recognise though that given the situation, I cannot deliver the mandate on which I was elected by the Conservative Party," Truss said in a brief statement outside 10 Downing Street.

Truss said she had spoken to King Charles III to notify him of her resignation and also met the 1922 Committee chair Sir Graham Bradywho has said a new Tory leader should be in place by "We have agreed that there will be a leadership election to be completed within the next week. This will ensure that we remain on a path to deliver our fiscal plans and maintain our countries economic stability and national security. I will remain as Prime Minister until a successor has been chosen," she said.

Truss said she had taken over at a time of great instability but ultimately admitted she had failed in her mission to deliver her economic agenda. Her resignation on her 45th day in office makes her the shortest-serving Prime Minister in Britain's history.

Rishi Sunak, who lost out to Truss' now failed tax-cutting agenda in the leadership race last month, is seen as a key contender to step up to the post. But the picture remains extremely uncertain due to deep infighting within Tory ranks. Loyalists of former prime minister Johnson believe the party should bring him back, given his solid electoral mandate from the 2019 general election. However, Truss' current troubles are themselves reminiscent of how Johnson was dragged out of office and forced to resign in early July amid an open revolt by a growing number of his MPs and ministers.

The latest develoopment comes a day after Home Secretary Braverman's explosive exit from the Cabinet after admitting a breach of the ministerial code by discussing government policy in private emails and a scathing parting attack on her boss. "Not only have we broken key pledges that were promised to our voters, but I have had serious concerns about this government's commitment to honouring manifesto commitments, such as reducing overall migration numbers and stopping illegal migration, particularly the dangerous small boat crossings," the Indian-origin former Home Secretary wrote in her resignation letter.
