I often wondered how David Cameron could have been stupid enough, what with all that expensive education, to think that a referendum on the EU would somehow pour oil on the troubled waters of the civil war in the Tory party between the people like Ken Clarke, Anna Soubry on the one hand, and Liam Fox, Jacob 18th Century and Michael Gove et al, on the other.
The barest intelligence would have concluded that bringing the argument, kept bubbling under for 40+ years, to the forefront of political life, was only likely to add oxygen to the fires of discontentment in his party.
Now it seems that Donald Tusk has released information about conversations they had which may throw some light on his motivations.
It appears that our esteemed ex-prime minister failed to realise how being associated with his toxic party had damaged the Liberal Democrats and that, as a result, their seats in parliament were so diminished that there was no coalition, but, in fact, rather surprisingly, a small majority for the Conservative party, and thus no coalition partner was available to stop the folly and take the blame.
(It was a small majority which his successor would manage, in, unbelievably, even more incompetent style, to lose.)
And as a result of his misjudgement, the Tory party, which he thought he could bring together with the referendum plan (and then blame the Liberal Democrats when it all fell apart) is now engaged in what seems to some may be a terminal civil war.
Oh well, if nothing else good comes out of Brexit, the damage that it will have done to the toxic Tories is a small chink of light in the darkness.
Of course, there is a far greater prize awaiting Scotland!
