we ve spent 4 1/2 decades in europe. we ve been part of the single market, trading relationships have grown up on the basis of we re part of that unique european system. you either stay close to that in which case you re going to keep to europe s rules, in which case people are going to say why are you doing this brexit? or you say we re going to make our own rules, we re going to break free from europe altogether but in which case it s going to costuts short-term and economically long-term painful damage. so that s the problem with brexit. and the negotiation by the way over these last 30 months has been an attempt by the prime minister and the government of finding a way of having our cake and eating it, of being part of the european trading system without keeping to its rules. that was never going to become possible. that s finally become apparent.
