What method do the Lib Dems use to choose their leader?
The candidates must be MPs. The members of the party are the electorate and they vote by giving preferences to the candidates. At any stage where no candidate has 50% plus one of the votes, the last placed candidate is eliminated with their ballots being transferred to the next numbered continuing candidate. The process is repeated until one candidate reaches the required number of votes to be elected.
So there's no requirement for support among fellow MPs before being put to the party members? Any MP who wants to stand for the leadership can do so carte blanche?
