Eurotunnel has issued an "urgent update for British residents in the EU" on its website and Twitter page. The statement reads: "Following a French Government decision, on 28/12/2021, unless they hold French residency, British citizens are now considered 3rd country citizens and can no longer transit France by road to reach their country of residence in the EU."
On December 18, Emmanuel Macron's Government announced a range of new rules on travel from the UK following a surge in the Omicron variant in Britain.
It means France now only allows travel from the UK for what it deems "compelling reasons".
The latest travel guidance from France states: "If you are of French nationality but you have your main residence in the United Kingdom, you are allowed, as well as your spouse (married, civil partnership, cohabiting partner) and your children (see supporting documents on 1.), to travel to the United Kingdom.
"You must be able to prove your main residence in the United Kingdom (title deed, lease, water, gas, electricity, internet bills, etc.).
"If you are of British nationality,you are allowed, as well as your spouse (married, civil partnership, cohabiting partner) and your children (see supporting documents in 1.), to travel to the United Kingdom, without guarantee of return to French territory, unless there is a compelling reason."
The French Government is yet to make an official announcement about the latest change in rules.
But the travel document and statement from Eurotunnel says the ban does not apply to British people living in France, or people from the UK that also hold an EU passport through dual nationality.
However, it still applies to British citizens living outside France in the EU.
