Brittany Ferries, meanwhile, hopes to reopen several suspended France-UK routes this month but is awaiting details of the UK’s new rules on foreign holidays (expected early May).
Apart from freight-only services, Brittany Ferries passengers with their own transport can currently use a weekly Portsmouth-Cherbourg service with the Galicia and a daily Portsmouth- Caen service with the Mont St Michel.
It is now taking bookings from May 17 for Poole-Cherbourg crossings with the Barfleur, Portsmouth-Saint-Malo crossings with Bretagne, and Plymouth-Roscoff crossings with Pont-Aven.
It is also accepting foot passenger bookings again from that date.
However, further postponements cannot be ruled out.
For the time being, the Portsmouth-Le Havre route is still only serving freight.
