The 1975 referendum took place under a Labour government and both major parties were in favour of continuing with our membership. I'd say that it's not possible to blame Heath (if you really must blame anybody) exclusively. The Labour Party connived, as did the electorate.

The Cameron regime put the poorest in this country through years of miserable austerity, which didn't have the effect he desired and which history will judge to have been completely unnecessary. His hubris convinced him that he would win the referendum. Instead, he pitched us into four useless years of wrangling and a dishonourable and shabby exit from the best trading bloc (among many other of its positive attributes) we could ever have belonged to. He gets my vote, though he is facing stiff competition from the present incumbent, and he will no doubt soon be overtaken in the crass stupidity stakes.
