A second P&O ferry has been detained following a safety inspection on the back of the firm sacking 800 staff so as to bring in cheaper agency workers.
The Maritime and Coastguard Agency (MCA) has said after undertaking a safety inspection it was "in the process" of holding The Pride of Kent on Monday.
The firm sparked outrage with protests at ports around the country after getting rid of 800 seafarers without giving notice on March 17.
