As Britain trundles towards a possible referendum on EU membership, people are beginning to ask what kind of result it might throw up.
David Cameron is gambling that if he manages to renegotiate some powers away from Brussels, voters will prefer this new settlement to not being in the union at all. And if past experience is to be believed, he has reason to be optimistic: when asked to assent to a plan from Brussels, voters across Europe tend to answer yes.
The list below of all the European plebiscites that have taken place in the union’s history shows that voters have only said no to the EU nine times out of the 36 referendums that have been held. The list was compiled by Matt Qvortrup, an expert on referendums at Cranfield University.
But those pushing for an exit from the EU will be heartened to see that voters appear to be getting more eurosceptic. Of the last six euro votes that have been held, three have resulted in a no vote.
