Boris Johnson and his crew knew exactly what was going to happen not too far down the line as far as trade with Northern Ireland was concerned, but he needed an 'oven ready' deal very quickly so he could win an election. He thought he could bluster his way out of any conflict with the E.U. as and when it happened.
He has given Europe yet another way to punish the people he is supposed to be protecting. He signed up to this ridiculous situation. He is only fit for campaigning. Sausages have lost a lot of their intrinsic humour now.
