THE labour movement demanded an immediate general election to end the “musical chairs at the top of government” today as multimillionaire Rishi Sunak prepared to be sworn in as the third Tory prime minister in just two months.

The former chancellor, whose resignation in July helped force Boris Johnson to resign in disgrace, was confirmed as the party’s fifth leader in six years after his only challenger, Leader of the Commons Penny Mordaunt, withdrew from the contest.

Mr Sunak will take office on Tuesday, becoming the country’s first British Asian premier, after King Charles III has accepted the resignation of six-week PM Liz Truss, whose disastrous mini-budget on September 23 sparked a run on the pound.
