Fishermen are halting exports to Europe because new border bureaucracy introduced by the government as part of Brexit is making their business unviable.

Exporters now have to deal with new health certificates, customs declarations and other paperwork if they want to sell to the EU, the largest market for much of the UK's catch.

Describing the situation as a "catastrophe", businesses said orders from Europe were also drying up because of Boris Johnson's new trade barriers.  

Seafood is highly perishable and relies on a seamless flow across borders, but small test consignments sent to France and Spain that would normally take one day are now taking three or more days, if they get through at all.

Who could possibly have predicted that leaving the common market and customs union and ending frictionless trade would have consequences? Especially for highly time-sensitive products? Who could possibly have imagined?
