Liz Truss has dramatically resigned as prime minister after just 45 days on the job.
The PM said her successor will be elected in a Tory leadership contest, to be completed in the next week.
Tory MPs urged Ms Truss to go after her government was engulfed by political turmoil, following the ditching of most of her economic policies.
Acording to the BBC, her resignation comes after a key minister quit and Tory MPs rebelled in a chaotic parliamentary vote.
Ms Truss was elected by the Tory membership in September, but she lost authority after a series of U-turns.
