Marriage (Same Sex Couples) Bill

My hon. Friend is making a compelling case for extending civil partnerships to opposite-sex couples. In fact, I have not detected any resistance to the idea in any part of the House, so there seems to be agreement that it would be beneficial. The point of argument is when it can be achieved, for the many reasons that he touched on. Benefits, pensions, inheritance and tax are very complex; it will take time to cost the proposal properly, rather than introducing it before we know exactly its implications.
