The Green party has a lot to answer for - including the backdoor Tory victory in my home constituency of Shipley. The previous Labour MP, Chris Leslie, was defeated by only 400 votes - while the Greens managed to garner 1800, almost entirely from Labour voters.

The result? We've ended up with an MP from a party that's far less environmentally minded than Labour, having consistently opposed environmental legislation in both Westminster and the European Parliament. Green voters in Shipley must be kicking themselves.
