Ferries and Channel Tunnel rail services were seeking to return to normal in the aftermath of a wildcat strike which shut the port of Calais for most of Tuesday.

More than 40 Eurostar services to and from London were cancelled, including some which had to return to their departure points after protestors breached security and accessed the tracks operated by Eurotunnel.

This led to chaotic scenes at St Pancras while further delays possible today with all trains fully booked from London and passengers urged to check in at least 45 minutes ahead of departure.

The port of Dover re-opened yesterday afternoon but leaving a massive backlog of lorries and cars due to cancelled ferries.

Eurotunnel and Eurostar expect normal services to resume today, while vessels operated by P&O Ferries, DFDS and MyFerryLink returned to operation last night.

The disruption was blamed on 100 crew from MyFerryLink staging an unauthorised blockade of the French port in protest over possible job losses through the sale of the former SeaFrance cross channel business by Euurotunnel to DFDS Seaways.

The situation was compounded by migrants trying to force their way onto UK-bound trucks in France.

Drivers returning to the UK were warned by the Foreign and Commonwealth Office to keep their car doors locked in slow moving traffic around Calais.
