Just to point out that the House of Commons voted that way - that's the combined vote of all parties eligible. The Conservative party was rather split on the issue, I think only a (largish) minority of the Conservative party itself voted in favour (although I can't remember the split offhand). That's still rather better than you would have got a few years ago, but then the Conservative party is now basically split down young/urban/secular-ish and older/rural/religious-ish lines and votes on these issues tend to be somewhat predictable.
