Ferry passengers are facing disruption as the Port of Calais remains temporarily closed today during an exercise to disarm two unexploded World War II mines.
The main access to Calais Port (Rocade), all ferry check-in booths, the UK Border Force and French Border Control booths have been closed from 7am French time.
They are expected to remain closed until 2.30pm French time, with queues and congestion expected in and around the Calais area.
P&O Ferries said customers can re-book their journeys free of charge and any cancellation fees "will be waived".
"We do advise that any day trips should be re-arranged for another day".
