I obviously agree with my hon. Friend that we should follow the law; there would not be much purpose to this place if we did not accept that premise.
The House of Lords Committee expressed an opinion. There are different opinions. I would probably accept that we do not need to pay all of that £39 billion. There are different views, and the hon. Member for Mansfield differentiated between some of them, but reneging on the entire £39 billion, as some Brexit extremists suggest we should, would put us in contravention of agreements.
