Northern Ireland Protocol Bill

It seems to me that the fundamental issue of debate is whether the EU would move on the implementation issues that it claims are the only problem. For the EU, it is not a question of renegotiation, but of implementation. It has said that it believes that customs formalities can be reduced by about 80%, and the same with sanitary and phytosanitary checks, and that the expanded trusted trader scheme could solve many of the problems. How confident is the hon. Gentleman that those things will be delivered, given how long this has been going on for and the affect already evident in Northern Ireland?
