France is reintroducing stricter rules on arrivals from the UK who are not French residents, the Foreign Office said.
The measures are an attempt to curb the spread of Covid, more specifically the Indian variant.
It comes after France said on Wednesday the British will have to quarantine upon arrival in the country.
In the latest measures, the Foreign Ministry has not yet defined “binding”, but the government has previously said that these could include family, health or professional reasons, reports France 24.
France relaxed the rule in March – but it will be reinstated on Monday.
However, it is understood that for the moment there will be “no systematic control” to ensure compliance with the requirement, “given the low incidence of Covid in Great Britain”.
France declared a mandatory quarantine period for arrivals from Britain on Wednesday, due to the increasing prevalence of a highly contagious variant of the coronavirus first detected in India.
France followed Austria, which said on Tuesday it was banning direct flights and sightseeing from Britain, and Germany, which on Friday said anyone entering from the UK should be put quarantined for two weeks upon arrival.
“There is a new situation with the progression of the so-called Indian variant in the UK,” government spokesman Gabriel Attal said.
“(France) will put in place compulsory isolation for people coming from the UK. “
The isolation will have to last for seven days, Clément Beaune, French Secretary of State for European Affairs, said on Twitter, adding that visitors should also present a Covid-19 test carried out less than 48 hours before departure.
The measures are expected to come into force on Monday.
The French government’s announcement will be a blow to part of the besieged tourism industry, which is desperate to get back to normal before the peak summer season.
“It’s reasonable to save the French summer but will be very penalizing for regions which depend on British holidaymakers,” said Ge Kusters, owner of Le Paradis campsite in Dordogne and president of the regional campsites union.
“Additional financial support will have to follow. “
Coronavirus infections in Britain have risen again, but the overall incidence is still low in a country with one of the fastest vaccine deployments in the world.
The number of Covid-19 hospital patients fell last week to its lowest level since September.
India’s B.1.617 variant clusters, however, rose rapidly to 3,424 last Thursday, up 2,111 from similar figures the week before.
The Indian variant has been reported in at least 17 countries.
