Three years ago it [public opinion] was strongly in favour of entry [into the EEC]. It may change again...and in any case I do not believe that it is… - Roy Jenkins

Those who had most insistently demanded the innovation of the referendum, because they thought it would produce exactly the opposite result, were temporarily stunned by the sudden revelation that they were populists without the support of the people. Now they have recovered from their concussion and seek to reopen the issue. ... Even if they had a coherent alternative policy, which they do not, it would wreck itself upon the rock of inconstancy. ... No one any longer expects us to be a rich country. But with an almost touching faith they still hope that we will be consistent and reliable. It is exactly this store of remaining national credit which the false democrats who first demanded and now deny the referendum seek to undermine.

[The effect of the Suez Crisis on the French was quite different.] We turned across the Atlantic. They turned across the Rhine, and Europe was built without us. There is room for argument about the causes of what followed. There is no doubt about what happened. Over the first 13 years of the [European] Community's life national income per head increased by 72 per cent in the Six and by 35 per cent in Britain. The result was that from being almost the richest country in Western Europe we became one of the poorest. France for the first time since the industrial revolution surpassed us in economic strength. The German economy achieved nearly twice our weight.

[A]lmost without a struggle, we have just witnessed a major lurch to the left in policy-making. The supreme authority of the Labour Party committed itself nine days ago to...a near neutralist and unilateralist position, which would make meaningless our continued membership of NATO...a commitment to practical non-cooperation with the European Community, leading in all likelihood to a firm proposal for complete withdrawal...a massive further extension of the public sector, despite the manifold unsolved problems which beset our nationalised industries, and mounting evidence from all over the world that full-scale state ownership is more successful in producing tyranny than in producing goods. Capitalism has its crisis today, but so too does estate socialism. There is now no economic philosopher's stone. But more successful nations are those which embrace a mixed economy and follow it with some consistency of purpose, not forever changing the frontiers. What remains of the private sector is to have enterprise squeezed out of it by being subjected to a straightjacket far tighter than in any other democratic country in the world.
This is not by any stretch of the imagination a social democratic programme. Nor do I believe that it is the way to protect Britain's security, help the peace of the world, revitalise our economy, or represent the views of the great majority of moderate left voters.
