Brexiteer Mark Francois claimed he has bet on himself to take over as Conservative leader.
The European Research Group (ERG) vice-chairman has said Theresa May would be out of a job this summer, and bet £10 on himself taking the reins.
"Light-heartedly I put £10 on myself at William Hill last weekend, really as a bet with a friend of mine, and I got the stunning odds of 200/1," he revealed.
"It's not impossible there will be an ERG candidate but that's unlikely to be me."
The MP for Rayleigh and Wickford previously challenged Labour's Keir Starmer to a £50 bet for Help for Heroes over the Brexit date.
Mr Francois bet that the Prime Minister would bring back her deal for a third vote on Tuesday March 26, but it was eventually held on Friday of that week.
He has publicly called for Mrs May to quit and backed 70 local Conservative associations in their call for an unprecedented early no confidence vote in her leadership, which is not allowed under existing rules until December.
However, Mr Francois predicted that the Prime Minister will not survive the European elections.
"One way or another, we're going to have a leadership election this summer, realistically," he said.
"That gives us time to pick a new leader before our party conference.
"I think after the EU elections, if the bookies are right and we have a pretty grim night, I think the 1922 executive will move, I think it's really quite likely they'll do it then.”
