The Port of Calais handles 9.7million passengers a year

Major developments at Calais are to be unveiled in London this evening that could result in more people coming to Dover.

The Port of Calais, which already handles 9.7 million passengers a year, is due to be doubled in size as a result of a €400million (£342m) investment by the French government.

Capacity will be significantly increased over the next five years and there are reports the French authorities might be planning to market Calais as "Britain's New Gateway".

Work is also due to start on a €300million (£256m) industrial park aimed at attracting more businesses to the Nord Pas de Calais region.
