As the book extensively documented, the two prime ministers who took us into “Europe”, Harold Macmillan and Edward Heath, were both made fully aware that the “Common Market” was only ever intended to be a front to the project’s real, long-term political intentions.  But in 1961 Macmillan told his Cabinet how vital it was that this must be kept out of view.  The deal must be sold to the British people as no more than an “economic arrangement”, affecting no more than trade and jobs – as was faithfully echoed by Heath in 1971.
