Eurostar is planning to operate a new route to Marseille next year.
The cross-Channel operator wants to run a London-Lille-Lyon-Marseille service from next spring.
Last year, it trialled a London-Lille-Lyon summer service over a six-week period.
A Eurostar spokesman told Business Traveller: "Following the success and popularity of our trial service direct to Lyon and Provence in the south of France during summer 2013, we made the decision to introduction a permanent, year-round service from 2015.
"Tickets will be available for sale towards the end of 2014 with the first services departing in the spring 2015. We expect to be able to announce in the autumn full details of the new service including fares and timetables."
Eurostar yesterday announced it has seen a 6 per cent increase in business travellers in the first half of this year (see news, July 17).
