Unwise words.

Hard to believe that as astute a politician as Vince Cable would make the comments ascribed to him recently of threatening to bring down the coalition government by resigning, but it goes further than that.  As far as the LibDems are concerned, coalition government is their Holy Grail.  Proportional representation is at the heart of their philosophy, and PR will almost always produce a coalition government.  So the LibDems have a vested interest in demonstrating to the country that coalition government works, and works well.  If this coalition fails - particularly if it fails as a result of something the LibDems do - then they might as well fold their tents and go off into the night.  They will be finished as any sort of a serious political party.  I'm sure Vince Cable appreciates this as much as anyone.
