The vote could go either way.
Only 36% of the British public oppose gay marriage so there is no real political danger to the government.
David Cameron is for it but the cabinet is split.
It will be a test for the Tories. Are they still the reactionary dinosaurs we think they are?
The minority of the public who do care about it do so with passion.
With emotions running high on both sides of the debate ahead of the House of Commons vote tomorrow, one MP told The Independent that a number of his colleagues were intending to vote for the Gay Marriage Bill because of the “appalling” nature of the emails they had received.
Meanwhile the gay Conservative MP Conor Burns, who has not publicly stated how he will vote, complained that he had been attacked from both the gay and Christian communities. “The whole thing is deeply unpleasant and people are saying things that you wouldn’t say to people you despised or hated,” he said. “I don’t know what kind of God some of those people who have contacted me from religious groups believe in – but he’s certainly not compassionate or loving.”
