You seem to have forgotten that the whole point of the Withdrawal Bill is to move certain EU laws and regulations into the domain of the U.K. Law. These laws are ones that could be moved, just like the rest. Or are you suggesting no laws at all should be moved under the Withdrawal Bill, in which case there would be no point in the government bringing the Bill in the first place.

I was never a hippy, by the way., as photos from my Univeristy days demonstrate.
