Representatives from the fishing industry which has a rich heritage across the east coast, are meeting Ministers to tell them what they should be aiming for during Brexit negotiations.

Lynn Shellfish employs 75 workers and has a multi-million pound turnover. The business which has been family run since it was established in the 1960s exports 95% of its product to the EU and the rest of the world.
The fishermen who work out of King's Lynn Docks for the company say there are too many EU rules and regulations which are holding them back.
Many of the fishermen at King's Lynn have at times struggled to earn a decent wage, with some having to take second jobs as labourers to make ends meet.
