Suppose for moment that the Conservatives had won the 1964 general election with say a ten or so seat majority, enough to last them the parliament. This pretty much guarantees a Labour victory come 1969 with a large majority and another in 1974 or whenever likely with a reduced one.
What I was interested in was what would Labour's–or more like the various groups with Labour and their supporters–attitude be to the idea of the UK joining the EEC? In our timeline it was Heath and a Conservative government that took us in whilst it was Wilson–who campaigned for Yes–and a Labour one which held the 1975 referendum on membership. Here it's Labour who are in charge when De Gaulle resigns and Pompidou takes over which opens the window of opportunity for Britain to successfully apply for membership.
