nope i thought you all used EURs over there, i thought that was the whole point of the EUR, everyone uses one currency.
As preparation for joining the Euro, we were meant to keep the pound within the limits of the European Exchange Rate Mechanism. Soros famously shorted Sterling on the advice of Druckenmiller, and John Major's government folded and abandoned it. We subsequently secured an opt-out in the Maastricht Treaty, unique I think, which meant we retained control of our currency.
