Eurotunnel's chairman and chief executive thinks Britain must remain part of the European Union when it votes in the Referendum - due this June.
Jacques Gounon was in Kent at the opening of a new freight check-in facility at Folkestone designed to get more lorries through the tunnel and take more traffic off the motorway.
The aim is to increase traffic flow through the Kent terminal by 300 vehicles per hour. This is part of the Terminal 2015 project, which includes expanding terminal capacity in Folkestone and Coquelles and putting three new freight shuttles into service.
Five new access lanes will bring traffic off the M20 at junction 11A.
We speak to Mr Gounon and to Damian Collins, MP for Folkestone & Hythe.
