UK residents in France and the Netherlands are facing a mad dash to get home as travel restrictions tighten.
On Thursday night, Transport Secretary Grant Shapps announced another massive curtailing of quarantine-free travel as the pool of countries it is safe to visit continues to shrink.
People arriving in the UK from both countries - as well as Monaco, Malta, Turks and Caicos and Aruba - after 4am on Saturday will be required to spend 14 days in self-isolation.
The move comes as many countries continue to see increases in Covid-19 cases and local outbreaks.
In response, French authorities have warned there will be reciprocal measures on passengers heading the other way, a double-blow to people with holidays booked in the country.
Airports and seaports are expected to see large numbers of returning passengers today as UK residents abroad rush to get home before the restrictions kick in.
Flights from both Amsterdam and Paris are due to land at Newcastle International Airport today, as well as the DFDS ferry from the Netherlands.
Channel Tunnel operator Getlink said additional services may be laid on but warned that many passengers may not be able to get back to the UK.
John Keefe, Getlink’s director of public affairs, told BBC’s Newsnight the trains were “already pretty much fully booked” on Friday.
He said: “We just haven’t got the space to take everybody who might suddenly want to come up to the coast. So what we are saying to people is amend your booking online, make sure there’s space before you travel to the terminal."
France’s secretary of state for European affairs said the UK decision would lead to “reciprocal measures” across the Channel.
Clement Beaune tweeted: “A British decision which we regret and which will lead to reciprocal measures, all in hoping for a return for normal as soon as possible.”
Transport secretary Jean-Baptiste Djebbari added that he had spoken to Mr Shapps about the decision.
He tweeted: “France regrets the British decision and will apply reciprocal measures in terms of transport.
“I told my counterpart Grant Shapps of our will to harmonise health protocols in order to ensure a high level of protection on both sides of the Channel.”
