Theresa May is expected to announce within weeks that the UK will reclaim its waters for British fishermen by pulling out of a deal that pre-dates the EU.

The Prime Minister will take Britain out of the 1964 London convention which allows European fishing vessels to access waters six to twelve nautical miles from British shores.

Pulling out of agreement would mean a clean slate for British fisherman after Brexit, although the Government could seek to secure a new deal during the negotiations.
