I have great respect for the right hon. Gentleman. Let me just say this, because the Leader of the Opposition in my view neglected to raise this important subject. My job is to uphold the integrity of the UK, but also to protect the Northern Irish peace process and the Good Friday agreement. To do that, we need a legal safety net to protect our country against extreme or irrational interpretations of the protocol that could lead to a border down the Irish sea in a way that I believe, and I think Members around the House believe, would be prejudicial to the interests of the Good Friday agreement and prejudicial to the interests of peace in our country. That has to be our priority.
