"Not only was it wrong for us to deal superficially with what Europe involved but we've paid the price ever since, because every time there's a crisis in Europe, people say with some justification, "Well, we wouldn't have been part of this if we'd really known the implications." Joining the European Community did involve significant loss of sovereignty but by telling the British people that was not involved I think the rest of the argument was prejudiced for the next thirty years."
