Would a fourth term Labour government try and take Britain into the euro?

Gordon Brown has done something great for Britain: he was one of the people most responsible for keeping this country out of the European single currency. As Chancellor, he was a roadblock to Blair’s ambitions on this front. So when the idea of Britain joining the euro was floated last weekend, I thought it was just Peter Mandelson getting too far forward on his skis and being a bit, from his perspective, too hopeful.
