They voted on the leadership two days ago. Unless they're going to have a revolving door where there's a leadership vote, the PM wins, two disaffected people sign a petition so they have another one, then the PM wins again, then they walk outside and two disaffected people sign a petition again so they have another vote ad infinitum. Very sensible of the PM to say that the result from two days ago stands or they'd be having a ballot for the leadership every half hour.
