The sole achievement of Gordon Brown as Second and then First Lord of the Treasury was to keep Britain out of the euro. I suspect this was inadvertent. Mr Brown was not a knee-jerk Europhile of the Mandelsonian variety. He engaged in that casual compliance with Europhilia that allowed much to be done by omission: not least, of course, the Treaty of Lisbon, and his shameful refusal to hold a referendum on it.
