Marriage (Same Sex Couples) Bill

Does my right hon. Friend accept that some of us may find ourselves having to abstain, even though that is not exactly ideal, because that is the only way of making the point that although what we are debating has merit, a conclusive case has not been made? I would like to make it clear that, although I am not implacably opposed to change, I need to be convinced that it is necessary and has been properly thought through. When I hear of Government lawyers who are not even able to deal with the basic detail of the change to marriage under new laws, I really despair.
