Is Wales about to become a permanent member of the UN Security Council?

From the little I've seen of Welsh First Minister Carwyn Jones on TV over the years (and the fact I've seen so little speaks volumes about the extent to which the broadcasters buy into the guff about the UK being a "partnership of nations") he's always seemed like a relatively impressive figure.  But his occasional contributions to the Scottish independence debate are making it increasingly obvious that he's actually a bit of a fantasist.  First of all, we had his bizarre claim that Wales would somehow "veto" an independent Scotland's entry into a currency union, in spite of the fact that a devolved territory within the UK cannot possibly have any say over such matters.  And now he's surpassed himself with the suggestion that the real "danger" of independence is that it might prompt England to "leave the union", with Wales and Northern Ireland ending up stranded -

"But it also means that I can see a scenario where in two or three years time there are calls in England to get out of the union with these expensive Celts in the west and over the Irish Sea.

If Scotland can leave the UK, so can England.

That leaves us and Northern Ireland."

Yeah, because of course the Westminster elite are famous for not wanting to rule as much territory as humanly possible. I do rather like that idea, though, because if the anti-independence propagandists are right, it would by definition mean that the remaining Welsh-Northern Irish union would be the sole legal successor state to the UK, and would be able to decide whether England should be "allowed" to continue using the pound. It would also take over from London as one of the world's five permitted nuclear weapons powers under international treaty arrangements, and would automatically become one of the five permanent members of the UN Security Council. England, by contrast, would naturally be thrown out of the EU and forced to join the euro (presumably on the same day).

Sounds far-fetched? "IT'S THE LAW!" screams Adam Tomkins (before demanding a written apology for your impertinence in thinking yourself worthy of sharing a planet with him).
