Richard Ballantyne, chief executive at the British Ports Association (BPA), said UK domestic cruises had demonstrated how ports and cruise lines could “ensure the health and safety of passengers, crew and destinations”.
He said the organisation is “hopeful that the devolved administrations will follow suit shortly” in allowing international cruises.
