Editorial: A welcome step towards gay marriage Even with opponents on the Tory right lining up to cause trouble, the prospects are promising. The Prime Minister is unlikely to be able to avoid the concession that Conservative MPs can "vote with their consciences" on the matter.

Statutory provision for same-sex marriage would not only be a victory for those who might wish to use it; it would be a victory for Britain as a liberal society. As such, every step closer is to be warmly welcomed.
