Lorries caught up in huge jams on the M20 heading for the Port of Dover are beginning to move after limited ferry services resumed, BBC News has reported.
A blockade at Calais by French ferry workers, which started on Monday (29 June), has been suspended, although the threat of further action remains.
Home Secretary Theresa May is due to discuss the problems with her French counterpart Bernard Cazeneuve in Paris.
According to BBC News, the Port of Calais is restricting entry to one ferry per hour, whileP&O said Calais port was open for traffic in both directions and it would sail every two hours from Dover to Calais.
The Port of Dover said it had no idea when the industrial action would end and Highways England predicted it would take until Monday (6 July) to clear the backlog.
Thousands of lorries remain stranded on the M20 in Kent, with the coastbound carriageway shut for 26 miles, although after ferry services resumed, the clear-up has reportedly begun to gather momentum.
