It’s always worth reminding ourselves of the realities Rees-Mogg ignores. And let’s be clear: he can’t ignore them. If we are to trade with the EU after March 2019 we have to give them data. If we can’t, we won’t trade. It really may well be that simple. They are not going to break their law to do so.
It’s so quaint to think that the EU obeys the law all the time, isn’t it?
