Brittany Ferries will close its Portsmouth-Cherbourg and Portsmouth-Le Havre routes next week following what it described as a "terrible" summer season, while warning yet of "weak forward demand" for autumn.
The company will take its Connemara ferry out of service from Monday (7 September), which is currently operating the two Portsmouth routes.
It follows previously advised closure of Brittany Ferries’ Portsmouth-St Malo route, which will also cease operating at the start of next week.
Poole-Cherbourg will also remain closed for the remainder of the year, having ceased operations at the end of March and not having resumed in June.
