A strike by SeaFrance staff, which led to the cancellation of cross-Channel services between Dover and Calais over the Easter break, has entered a fifth day.
The dispute is estimated to have cost the French ferry operator more than £1m, with tens of thousands of passengers affected over the bank holiday weekend.
Talks aimed at resolving the dispute are continuing following the cancellation of all SeaFrance cross-Channel sailings since Friday. Services are expected to resume 2000 BST on Tuesday.
The industrial action began when members of the CFDT union walked out in a row over new working practices.
SeaFrance has advised customers to arrive as normal, saying they will be transferred to a crossing with another operator.
In a statement, the firm said it “profusely apologised” to those affected.
The ferry company normally operates 16 to 19 crossings a day between Calais and Dover.
SeaFrance said negotiations had been taking place to find a solution to the industrial dispute.
