My Lords, perhaps I may be able to help the noble Lord, Lord Elton. As it stands, as I said earlier, the Marriage (Same-Sex Couples) Act 2013 does not allow for clergy of the Church of England to solemnise, but it makes provision for other religions, including Quakers and Judaism, to opt in. There is no obligation; there is an opportunity to opt in to solemnise. They are not obliged. If as individuals or a group they do not wish to solemnise, there is no obligation to do so.
