On 18 January more than twenty shellfish trucks parked just metres from Boris Johnson’s Downing Street office and the British parliament to protest against the post-Brexit bureaucracy that has stopped them exporting to the EU. Many Scottish fishermen have not been able to export their stocks to Europe since the start of the year after the introduction of catch certificates, health checks and customs declarations added lengthy delays to their delivery times, prompting European buyers to reject them. A director of Venture Seafoods, which exports live and processed crabs and lobsters to the EU. said he had cancelled several lorries due to the onerous red tape involved. One operator needed 400 pages of export documentation last week to board a ferry to the EU. He warned the system could collapse.
