If only they could have gotten fewer than 100 MPs; then by their own party rules they wouldn't even be able to nominate a new party leader.
As it is, any potential new Tory party leader needs a large supermajority of Tory MPs just to be nominated.
I wish that was true, but the 1922 committee changes the rules whenever they feel like it. All the big UK political parties have rules written on water.
At least a “large supermajority of Tories” is something that’ll take some doing to make happen, they liked infighting before and now they’ll be eating themselves.
