My Lords, this is a really important issue and one that we need to clarify. I am sure that there are international obligations to do this, but I would be very interested to hear what they are. The noble Baroness raises some really important points about the fact that at sea, things can get difficult and emotional. We saw the incidents in the Baie de Seine last year or the year before, so we have to be very clear and careful about some of these things.
One thing I want to point out, which the Minister will be completely aware of, is that we sometimes envision an EEZ where foreign vessels have to stay on one side and British ones on the other; but under international convention, as long as they are steaming and not fishing, they are absolutely allowed to go through international waters. It is important to remember in this debate that it is not all about keeping foreign fishing vessels out of the UK EEZ; they are perfectly entitled to be there, not necessarily in territorial waters but between 12 miles and the median line, or 200 nautical miles. They are entirely allowed to steam through there as long as they do not fish, and we should remind people of that.
