No EEC poll
In the abstract, William Ballantine’s suggestion of a 60 per cent threshold for change when a referendum is held sounds sensible. However, had a referendum been held prior to the UK joining the EEC in 1973, it is unlikely that this threshold would have been met (public opinion seems to have been fairly equally divided at that time) and clearly the then Government did not believe it could obtain even a simple majority if a referendum had been held before greater powers were given to the EU under the Lisbon Treaty. It would be a curious thing if the public were given no vote at all before joining an organisation but were then told that it took a 60 per cent vote to leave.
