The UK government has announced plans to force all people arriving through its ports and airports to go into quarantine for 14 days. It is not yet known when the new measures will take effect.
Passengers from the Channel Islands will be exempt, but anyone arriving in Jersey, from the UK or elsewhere, will have to self-isolate for 14 days.
Condor Ferries had previously said it hoped to restart its passenger services around the middle of the month, but the Liberation, which travels to Poole, will now remain in port until at least 12 June.
The Commodore Clipper, which is currently only running a freight service, will also not resume its passenger operations until at least the same date. And the Rapide, which sails to St Malo, is cancelled until 14 June.
A spokesman said the company was keen to reinstate passenger sailings as soon as possible.
In a statement online, Condor said: ‘Everyone affected by the suspension will be offered a rebooking or travel voucher which is valid for 18 months.
‘Our contact teams will be extremely busy during this period and ask for your patience due to the unprecedented changes to the schedule.’
In his address to the nation on Sunday evening, UK Prime Minister Boris Johnson said the time had come for a quarantine to be put on people arriving in the UK.
He said: ‘I am serving notice that it will soon be the time – with transmission significantly lower – to impose quarantine on people coming into this country by air.’
The government later clarified that the rules covered all forms of travel into the country.
