It has been an unrelenting, but, I have to accept, at least partly successful campaign to persuade Britain that Europe is a conspiracy aimed at us, rather than a partnership designed for us and others to pursue our national interest properly in a modern, interdependent world. It is right to confront this campaign head on. Provided that the treaty embodies the essential British positions, we shall agree to it as a Government. Once agreed – either at the June Council, which is our preference, or subsequently – Parliament should debate it in detail and decide upon it. Then, let the people have the final say.
