Supplies of iconic British seafoods such as prawn sandwiches and fish and chips are being threatened by lack of a trade agreement with Greenland following the UK's departure from the European Union under Brexit.

This is according to a report by All-Parliamentary Group for Greenland Director Dwayne Menezes in his role as founder and director of the Polar Research and Policy Initiative think tank.

Greenland, an autonomous Danish dependent territory, is the UK's largest source of imported coldwater prawns and significant quantities of other North Atlantic seafood such as cod, haddock, halibut and snow crab.
