You didn't provide the link, but I assume you are referring to this article:

I remain confused, though, by the claim that, "After Brexit, the UK will be entitled under international law to lay claim to an EEZ up to 200 miles from its coast, within which the British Government will police how fishing operates."
As I said, the UK already has a large EEZ, one of the largest in the world, but locally the 200-mile limit clearly doesn't apply (since, after all, a good deal of that limit would overlap with the same claims made by France, Norway, Iceland, Ireland, Denmark, Sweden, Spain etc). International law covers these cases, but I think that the UK's EEZ is already locally as large as it will ever be.
In the long run it makes sense that the UK leaves the EU's fisheries policy, but I wonder if people are assuming that this also means expanding our own personal waters when that's almost certainly impossible.
