Britain's interim Leader of the Opposition Rishi Sunak has used his final address as Conservative Party chief to call on his colleagues to stop squabbling and unite behind his successor

It was a curious farewell for Rishi Sunak this afternoon. The Tory leader has just finished his final speech to the party faithful before handing over the reins in five weeks time.

Rishi Sunak has officially made his last ever conference speech as the leader of the Conservative Party. The party’s annual gathering usually has those at the top leading the whole event, but the former PM – who is still leader until November – has taken the almost unprecedented step of not speaking from the main stage at all this year.
