In the debate on the Second reading of the Referendum Bill (voted through by a landslide of most MPs except the Scottish Nationalists), there was a golden opportunity for MPS to insist that plans were in place whatever the Referendum outcome. As far as I can see, nobody did. I find it hard to take criticism now for voting Leave from MPs that voted for a Referendum and did not take the obvious possibility of a Leave vote into consideration.
Euroscepiticsim is not, as some seem to suggest, something new. It probably started in 1960 with Hugh Gaitskill, the Labour leader, and has ebbed and flowed ever since. Its early roots, and major part now, were about sovereignty. Successive governments have passed more and more powers to the EU without referring to the public. When they have asked the public, the majority said Leave.
When the UK voted to Remain in 1975, 33% of the voting public were disappointed but accepted the judgement of the majority. How times change.
