Mallochs?

Lord Malloch-Brown is said to favour a single EU seat on the UN Security Council. Well, the French will never consider that for one moment, so he can forget it. But the Constitreaty will require any member-state with such a seat, permanent or otherwise, to use it as directed by the EU Foreign Minister. What are the odds that the man Lord Malloch-Brown, and indeed Gordon Brown, favour for that office is none other than Mark Malloch Brown? And would he still attend British Cabinet meeting if he got it?
