Watch the moment Rishi Sunak makes his final speech outside 10 Downing Street after a historic election defeat to the Labour Party. Speaking on Friday 5 July, the outgoing prime minister apologised after leading the Conservatives to their worst ever result as a Labour landslide swept Sir Keir Starmer to No 10. Mr Sunak said he would quit as Tory leader once arrangements are in place to choose his successor, potentially triggering another round of Conservative infighting as MPs scramble to replace him. Sir Keir will become prime minister after a Tory rout which saw former premier Liz Truss and a dozen serving cabinet members lose their seats.
