The train service announced it had lowered its estimation of earnings for the year by 4.5% to €535m (£447m) following the UK’s decision to leave the European Union last month.

The company also cut its profit forecast for 2017 by 4.3%.

Eurotunnel made the alterations to its books after calculating the value of the pound to be 7% lower against the euro - reducing profits once the currency had been converted back.

Following the referendum result the rail operator saw shares fall by 30%.

According to the BBC, Eurotunnel believed Brexit’s effect on the number of cross-Channel travellers to be uncertain but did not foresee any significant impact in the short term.

Chief executive Jacques Gounon said: "Despite the financial market uncertainty generated by the United Kingdom voting to leave the European Union, the group remains confident in the performance of its economic model and in its outlook."

Away from Brexit, Eurotunnel’s business was affected after terror attacks in Brussels and rail strikes around Europe prompted a 3% fall in passenger numbers for the first half of 2016.

Despite the set-back, truck shuttle traffic experienced a 10% rise in the same period and overall profits in the first half of the year rose 4% to €249m (£207m).

Two thirds of the company’s income comes from vehicle shuttle services – with UK customers making up 80% of its car passengers.
