The vote on the A.V. or Alternative Voting system based on proportional representation is causing a split in the Liberal Democrat- Conservative coaltiion government. Liberal Democrats favor the A.V. because it estimates that under that system it would have won 30 more seats in addition to the 57 it won in the last election. This was also a key condition of the Liberal Democrats to join the government. Now Liberal Democrat Vince Cable and others are saying they see a Labor- Liberal Democrat coalition as a "progressive majority" preferable to an alliance with the Conservatives, which only gives power to " a right wing clique that wants to keep things as they are." This is happening as Britain faces local elections, and the Liberal Democrat participation in the government is becoming deeply unpopular with the rank and file party members.
