The hon. Gentleman makes a very good point. Those who advocate further negotiation with the EU need to persuade the EU to change its negotiating mandate so the text of the protocol can change, because we know that those specific issues, including on the customs bureaucracy and VAT, can only be addressed by addressing the text of the protocol itself.
I want to come on to the specific point the hon. Gentleman made about article 16. Of course we have looked at triggering article 16 to deal with this issue; however, we came to the conclusion that it would not resolve the fundamental issues in the protocol. It is only a temporary measure and it would only treat some of the symptoms without fixing the root cause of the problems, which are baked into the protocol text itself. It could also lead to attrition and litigation with the EU while not delivering sufficient change.
I want to be clear: we do not rule out using article 16 further down the line if the circumstances demand it, but in order to fix the very real problems in Northern Ireland and get the political institutions back up and running, the only solution that is effective and provides a comprehensive and durable solution is this Bill.
