Brown has been printing money. The Pound has become devalued. The BoE is not chartered to manage the value of currency directly, so it has only interest rates which it is under pressure to reduce, let alone raise. Of course, the Libertarian Party saw the threat to the currency some time ago. It has a manifesto commitment to reform monetary policy and at the centre is the drive to maintain the value of the currency.
I suspect now will be a time that Brown, the traitor, will consider joining the Euro. The EU will be delighted in private, but in public will huff and puff about it, then only agree after harsh penalties have been imposed (e.g. the Treasury loses any vestiges of fiscal sovereignty). Brown will agree as long as he has a sinecure at the IMF or ECB sewn up for himself. Darling will be on a promise, to keep him quiet.
Something, though, makes me think that this may not happen. Brown, for all is "son of the manse" artifice, has an ego the size of Greenland. He thinks he is the architect of the recovery, the Captain in the teeth of the storm. If it still looks like he will lose the next election, I would not put it past him to lay the foundations for the UK to be bounced into such a deal. Super Dave Cameron has not shown himself to be interested enough in Sovereignty, so I do not trust him. The LibDems are, as always, beyond the pale*.
* I wish those in the Lib Dem Party who call themselves "Libertarian" will face up to the fact and get out of that rancid organisation.
