Eurotunnel achieved record revenues of more than €1bn in 2013, a rise of 12%.

As well as taking €1.092bn (£893m), the Channel Tunnel operator also broke the 10m passenger barrier on its high speed trains for the first time.

Its rail freight service Europorte also showed impressive growth, with revenue up 16% to €238.5m (£195m).

The operator also benefitted from new activity in the Dover to Calais market, after its acquisition of three ferries from SeaFrance after the company went into administration.

Leased to independent company SCOP SeaFrance, the service saw revenues increase dramatically from €7m (£5.7m) in 2012 to €74m (£60.5m) in 2013.

However, these revenues could be short lived as the venture is still the subject of an investigation by the Competition Commission.

A decision is due in April on whether the group bought assets or took over SeaFrance, the company, after it was went into administration at the end of April 2012.

Groupe Eurotunnel chairman and chief executive Jacques Gounon said: “Eurotunnel has had a record year and, in spite of the highly competitive market situation, has delivered revenues significantly above one billion euros.

“For its 20th Anniversary in 2014, the group has confirmed its capacity to make the most of the recent economic growth in Europe and particularly in the United Kingdom.”
