The government has taken the first step on the way to what it calls "taking back control of our waters" - something the region's Brexit-supporting fishermen have been calling for for years.

A fisherman from Essex says the government's decision to withdraw from a deal that allows other countries to fish in its waters could offer a massive boost to the industry in this region.
Paul Gilson, from Leigh on Sea, has been fishing for nearly 50 years. He welcomes news the UK will pull out of the London Fisheries Convention.
Mr Gilson wants the UK to take back control of its waters because he believes the EU has made a mess of the fishing industry.
At the moment, the convention allows vessels from France, Belgium, Germany, Ireland and the Netherlands to fish within six to12 nautical miles of the UK's coastline. That is in addition to the EU Common Fisheries Policy that gives European boats access to waters from 12 to 200 nautical miles.
Mr Gilson said the current rules had decimated the industry in the East of England.
The government will notify the other member states signed up to the agreement on Monday. The change in regulation is expected to come into play in two years' time.
Environment Secretary Michael Gove said this move allowed the UK to put itself in a better position ahead of Brexit, when the country would no longer be bound by the Common Fisheries Policy either.
