Constitutional Reform and Governance Bill (Money) (No. 3)

In one second. All the major parties represented here have at the heart of the election of their leaders an electoral system that involves the progressive elimination of candidates. Sometimes elimination rounds are used. The Conservative party conducts sequential votes when there are more than two candidates, until the final two candidates are put to the membership. The Liberal Democrats use the single transferable vote, which amounts to the alternative vote when there is only a single post to be filled. The Labour party has long used the alternative vote for the election of its leader and deputy leader. It used to have lengthy eliminating ballots for local selections, but has now generally moved to the alternative vote system.
