The author is Benjamin Grob-Fitzgibbon and the subtitle is Britain and Europe from the End of Empire to the rise of Euroscepticism. It is maybe the best book to read on Britain’s earlier relations with the European Union. Here is one bit:

The vast majority of the Labour Party was anti-EEC, believing that it was a capitalist conspiracy that would undermine Britain’s control of its own industry.

That was during the 1960s. And this:

When it awoke on the morning of 1 January 1973 as a full member of the European Economic Community (EEC), the British public was deeply ambivalent. In a poll taken 3-7 January 1973, 36 percent of the public reported being ‘quite or very pleased’; 33 percent were ‘quite or very displeased’ and an astonishing 20 percent purported to be ‘indifferent’ (the remaining 11 p cent were undecided, but not indifferent.

By August 1973, 52 per cent were opposed and only 32 per cent still in favor.

Definitely recommended, a book for our times.
