The head of Eurotunnel on Thursday blamed "British protectionism" for triggering a wave of strikes by French ferry workers that disrupted freight and passenger travel on both sides of the Channel.
The company, which manages the Channel Tunnel and its vehicle shuttle services, also owns three ships that operate under the brand name MyFerryLink, which it bought from bankrupt French carrier SeaFrance in 2012.
But that transaction has been fraught with legal complications and early this year, a British tribunal halted MyFerryLink services from the southern English port of Dover to France's Calais on grounds of unfair competition.
An appeals court later overturned the ban, but Eurotunnel nevertheless decided to sell two ferries to Danish operator DFDS, a move expected to result in hundreds of job losses that triggered last month's hugely disruptive strikes.
"The current situation in Calais, which is terrible, is not due to a Eurotunnel decision," Jacques Gounon told a parliamentary commission in Paris.
He said it was a result of the British competition commission "continuously defending" British ferry giant P&O and being allowed to "block any development... under a French flag."
"It's British protectionism that is forcing us to stop this activity."
He defended Eurotunnel's decision to sell the ferries to DFDS, which he described as a "ferocious competitor" on the Calais to Dover route that wants to challenge British ferry giant P&O.
"It was unreasonable in my opinion to further reinforce P&O which is the maritime leader... DFDS was an operator that needed ships and employees," Gounon said.
