Senior Tories are jockeying for position to succeed doomed Boris Johnson, as the Prime Minister is set to resign with a statement later today.
Following a flood of sleaze scandals including Partygate and the Chris Pincher furore, Mr Johnson’s time in No10 looks to finally be over.
Since Tuesday night, more than 50 Tory MPs have abandoned their leader and staff at Number 10 have now said his letter of resignation has been prepared.
The statement is expected to be made at lunchtime - but who could replace the outgoing PM as leader of the Conservative Party.
Penny Mordaunt has emerged as the hot favourite to become PM.
Rishi Sunak, Liz Truss, Ben Wallace and Sajid Javid are widely tipped to stand.
After a bruising charge to oust their boss, MPs are set to enter a potentially divisive bid to choose a fresh direction.
But can anyone unite the party split over Brexit and Mr Johnson’s shameless conduct?
Here Pippa Crerar, Ben Glaze and Rachel Wearmouth look at the contenders to become PM.
