The Channel Tunnel has reopened after a three-hour shut down caused by striking ferry workers who lit fires on the tracks.
In a day when a mix of striking ferry workers and desperate migrants caused transport chaos to travellers on both sides of the Channel, P&O Ferries chief executive Helen Deeble hit out with with fierce criticism toward the British and French governments, as well as Eurotunnel.
In a statement she said: "And when is the British Government going to stand up to ensure that we can all get to mainland Europe safely and securely? Every day that the disruption lasts costs UK Plc millions of pounds."
She pointed out that P&O Ferries employs thousands of people on both sides of the Channel and "this damaging and dangerous industrial action is now putting those jobs at risk".
She added: "Let me be clear: the buck stops with the French government. They have shown that they can move swiftly to stop any disruption at the tunnel.
"But they have effectively abandoned any attempt to maintain security at the port of Calais, which makes a nonsense of European co-operation.
Ms Deeble also blamed Eurotunnel for putting passengers in the middle of an industrial relations battle by not securing the jobs of workers involved.
Ferry services to and from Dover in Kent have been hit by the strike, which started at the northern French port at 2.20pm yesterday.
A Eurotunnel spokesman said: "Services restarted through the Channel Tunnel at 15.50 this afternoon. Eurotunnel will build up services progressively through this afternoon and this evening."
"We will be intending to get back to normal service as soon possible."
