Eurostar has warned of continued disruption to services between London and Paris due to strike action by French customs officials.

Three trains have been cancelled today, two tomorrow and a further three on Wednesday.

This follows four departures being cut yesterday, with the high speed Channel tunnel passenger rail service warning people not to travel “unless absolutely necessary”.

This follows delays of more than five hours on Saturday due to congestion at Paris Gare Du Nord station.

The company said: “All Eurostar trains are experiencing delays and long queues for journeys from Paris Nord due to industrial action by French customs until March 19.

“These delays impact our planned timetables and cause subsequent cancellations.”

The impact of industrial action is compounding existing problems on the service which is running a reduced timetable until March 30 due to unspecified “operational reasons”.

Up to three services a day between London St Pancras and Paris have been cancelled over the 13 day period.

Refunds or ticket exchanges o to other services are being offered.

All unions representing customs officers working at Paris Charles de Gaulle airport also called for strikes until April 1.

Customs officers are demanding higher pay and better working conditions.

They also want more staff which they say will be needed after Brexit, to help process British citizens who will no longer have European Union passports.

French unions representing around 17,000 customs workers last week rejected a government offer of a €14 million pay boost, saying it was not enough.
