UK Prime Minister Boris Johnson is set to resign on Thursday.
It's understood Mr Johnson has spoken to Tory 1922 Committee chairman Sir Graham Brady and agreed to stand down, with a new Tory leader set to be in place by the party conference in October, a No 10 source said.
An official announcement is due later today when Mr Johnson makes a public address. He is expected to remain PM over the summer while a new leader of the Conservative Party is elected.
