I thank the Home Secretary for giving way. The legal advice released this morning makes it clear that the protocol does not provide for a mechanism that is likely to enable the UK lawfully to exit the UK-wide customs union without a subsequent agreement. It goes on to say:
“This remains the case even if parties are still negotiating many years later, and if the parties believe that talks have clearly broken down and there is no prospect of a future relationship agreement.”
Does that not undermine the point that he made a moment ago when he argued that this arrangement was not sustainable in the long term because of the limitations of article 50? The advice of the Attorney General is that it is going to last.
