"Labour today comes the closest yet to suggesting that its supporters vote tactically in constituencies where the main battle is between the Liberal Democrats and the Conservatives.
"In an interview with The Independent, the cabinet minister Peter Hain urged people to "vote with their heads, not their hearts" as he issued a last-minute appeal to supporters of other parties to rally behind Labour "for the only time in their life" to stop David Cameron becoming Prime Minister in Thursday's election.
""I support every Labour candidate and the Liberal Democrat leadership supports every Liberal Democrat candidate. But voters are intelligent and they know what the real fight is in their own constituency. They will draw their own conclusions," he said."
