Not a greeny apart from when in uniform, but I'd applaud conservation.Providing EU trawlers are genuinely shut out of UK waters (substantially reducing the tonnage of fish taken) and conservation is sensible, there is capacity for both UK trawlers to earn a decent living and fish stocks to recover.
The other predictable thing is that the EU won't cut back their limits accordingly, which will result in EU waters being severely over-fished over the next decade.
Finally, BoJo can give the EU a big political headache over this. He needs to announce significant cutbacks in the catch from UK waters and state that's because of past EU policies and the need to let fish stocks recover. Which will be applauded by conservationists.
(That'll give the Greens on the continent a big headache. Do they side with the EU or the cutbacks...)
Pay the UK fishermen compo based on filed tax returns, for a year or two. Anyone else can do one.
Then get the Icelanders and Norwegians over to show us how to manage the resource.
