Channel tunnel operator Eurotunnel has asked the UK and France to reimburse losses of 29 million euro (£22m) caused by the migrant crisis in the port of Calais last year.

Eurotunnel made the claim via the Intergovernmental Commission as it revealed a 22% dividend increase to be proposed at its AGM on April 27.

Announcing its annual results, the company said: "The security of the fixed link being the responsibility of the two governments, a claim for €29m has been made via the intergovernmental commission to compensate essentially the revenue losses due to migrant pressure."

There was heavy disruption to Eurotunnel services last summer as migrants based at the 'Jungle' camp in Calais made repeated bids to board UK-bound freight.

Night services were suspended on and off between June and September with the number of trains running through the tunnel last year to falling by 17%.

But Eurotunnel said there has been no disruption to services since last October following strengthened border security at Coquelles.

Revenues for the company increased by 5% to 1.2 billion euro (£926 million) compared to 2014, the company said.

And the group's pre-tax profit for 2015 was 115 million euro (£89 million), an improvement of 25 million euro (£19 million) compared to 2014.
