Ricky finds out what's been happening since the PM resigned

Sir Keir Starmer has announced that he'll be leaving his job as prime minister and as leader of the Labour Party.

That means someone else will need to replace him, and at the moment most people think that could be Andy Burnham.

He was elected last week as the member of parliament for Makerfield and has now been officially sworn in as MP.

Ricky has been speaking to BBC Political Editor Chris Mason about what might happen next.
