The UK Prime Minister had a 2% advantage from the Brexit vote to enter into EU negotiations. That was sufficient. That was Politics. That was not enough for the elite who were used to getting it all, from a slow burning 6-7 % return on investment to several hundred percentage gains, also called The Lot.
Next week's election may yet be interesting. Will the Remainers have their revenge for Brexit? If the Prime Minister loses 3% or more compared to the Brexit vote, then face is lost, if not already. Theresa May is playing for The Mythical Lot.
