Liz Truss said on Thursday she was resigning as prime minister, brought down by her economic programme that sent shockwaves through the markets and divided her Conservative Party just six weeks after she was appointed.
A leadership election will be completed within the next week.
Speaking outside the door of her Number 10 Downing Street office, Truss accepted that she could not deliver the promises she made when she was running for Conservative leader, having lost the faith of her party.
