Yes, my Lords. I have committed to write in relation to that and I will pick up other questions that have been raised, including by the noble
Lord. Obviously, there are existing international agreements that are, if you like, deposited, and which we have to work with, as well as issues of how we move forward case by case, but I will certainly address in a letter the point the noble Lord asks about. It is a legitimate question. The status of international agreements was also raised from the Front Bench opposite, and I will write to the noble Lord on that matter and copy it to colleagues in the Committee.
