...we must recognise that the greatest threat to the cohesion of our society today is the still increasing rate of inflation. ... We are approaching … - Roy Jenkins

What is more likely [if there were a referendum]...is that party loyalties would be strongly mobilized and that in order to frustrate the government of the day the Opposition would form a temporary coalition of those who, whatever their political views, were against the proposed action. By this means we would have forged a more powerful continuing weapon against progressive legislation than anything we have known in this country since the curbing of the absolute powers of the old House of Lords. Apart from the obvious example of capital punishment, I would not in these circumstances fancy the chances, to take a few random but important examples, of many measures to improve race relations, or to extend public ownership, or to advance the right of individual dissent, or to introduce the planning restraints which will become increasingly necessary if our society is to avoid strangling itself.

My central belief is that there are only two coherent British attitudes to Europe. One is to participate fully in all the main activities of the Union and to endeavour to exercise as much influence and gain as much benefit as possible from inside. The other is to recognise that Britain's history, national psychology and political culture may be such that we can never be other than a foot-dragging and constantly complaining member. If so, it would be better, and certainly would produce less friction, to accept this and to move towards an orderly and, if possible, reasonably amicable withdrawal.

Were we to leave [the EEC], the worst damage would be done to ourselves. But not only damage. Western unity, at a time of great international danger, is under greater strain than at any time since it was put together in the aftermath of the war a generation ago. Were we to start to disengage, the whole delicate but precious structure might begin to fall apart.
