The line’s services have been suspended since it sacked nearly 800 of its UK seafarers last month and sought to replace them with lower paid agency workers instead.
On Wednesday (6 April), P&O Ferries said it was ready to restart several "vital services" at the weekend, including its Dover-Calais route.
However, on Friday morning (8 April), the line tweeted: "All P&O Ferries passenger services are suspended this weekend. For travel 8/9/10 April, please rebook directly with another operator before arriving at the port."
