Of course I am privileged by having been paid in a previous existence to plan and execute industrial relations negotiations where a decimal point or two on a paybill of several £billion could end up as serious money, but the greatest crime of this government was naively thinking that the big hitters of the EU were their friends and would happily reach an amicable agreement etc etc.
I think Margaret Thatcher's advice would have been "Theresa, think of the EU as the NUM and you won't go far wrong".
