Further to that point, which is a very good one, would the EU not decide to use its powers if Stormont tried to use the brake too often and change the amount of EU law that applied?
The Stormont brake was the result of a negotiation between the Government and the European Union. It was a really big step forward—it is why we are having this discussion now, and I support it. Anything is possible in the future with regard to what one or another party that is engaged in continuing discussions and negotiations may seek to do, but we have a deal with the European Union and it expects us to honour the Windsor framework—a point I have made in the House many times before—and we would expect the EU to do entirely the same. Nobody can guard with absolute certainty against what may happen in the future; we have to deal with the world as it is today.
