Channel Tunnel shuttle train services run by Eurotunnel are facing the threat of strike action by French unions over the Bank Holiday weekend.

Eurotunnel said it was not taking further bookings for journeys between Calais and Folkestone for Saturday, Sunday and Bank Holiday Monday. But the company said it still hoped to run a full service over the weekend.

French workers were demanding an 8 per cent pay rise and were threatening to strike from Saturday. The company said it was taking all steps to mitigate any disruption by ensuring British train drivers were available. Eurotunnel is also looking into the possibility of sending British staff to man the terminal in France.
