I urge my hon. Friend not to move on too fast, but to come back to the word "federal" for a moment. I seem to remember that the dropping of the dreaded F-word was a considerable negotiating triumph, and I suspect that that is so. We now hear from the hon. Member for Inverness, Nairn and Lochaber (Sir R. Johnston) that federalism is a decentralising concept. If there are those two opposing ideas, can my hon. Friend put his mind to why the Liberals should be voting in the same Lobby as some of our colleagues?
