A lot would depend on the nature of the agreement. If it is part of a wider treaty, we may well see further legislation. However, our understanding is that if we can achieve agreement on this area, we would look to implement it rapidly through regulation, which is why the power is in the Bill. Our priority would be to avoid a situation where something is agreed of benefit to both UK citizens going to live in the European Union and EEA citizens coming to live here, with which we and the European Union are happy, but we are unable to provide that benefit because we are still going through a parliamentary process to implement it. That is why we believe the clause to be appropriate. It allows us to react to circumstances as necessary.
