Great Britain's port officials are sitting uneasily over Prime Minister Theresa May's decision today to delay Parliament's vote on her Brexit plan.

British Ports Association (BPA) chief executive Richard Ballantyne said ports involved in EU trade and the wider logistics sector are "anxious" to know what they need to do in the event of a "no-deal" departure.

“If there is a hard Brexit the roll-on roll ports who facilitate tens of thousands of lorry and trailers movements between Britain and Europe every day could face real challenges," he said.
