I suppose I agree, rather weakly, with the proposition that it is better to elect someone with the acceptance of the majority in the constituency rather than the enthusiastic support of a minority.

But Bliar won the last general election with only 35% of the votes cast – a fact he conveniently forgets as he continually reminds us he won three elections. The AV system would probably have actually increased New Labour’s majority in parliament in 2005.

The logical contradiction of a system which at constituency level ensures majority acceptance, but at the national level would give an even bigger majority to a party supported by only 35% of those voting, is a fatal flaw in the argument.

Plainly the system needs to be changed so a dangerous fanatic like Blair cannot reach power when his party has only 35% voter support. The way to do that is by single transferable vote in multi member constituencies.

Any referendum which does not include the option for real change is pointless.
