Dr Robert Saunders appeared on BBC Breakfast news to discuss the EU referendum (link is external). The coming referendum will be the second time that the British public have been called upon to vote on the UK's participation in Europe. Forty years ago 67 per cent of British voters said yes to the question "Do you think the UK should stay in the European Community (Common Market)?" Dr Saunders looks back at the archive to see if any lessons can be learned.
