Foreign Secretary Dominic Raab has urged all British nationals to leave China in the wake of the coronavirus outbreak.
The plea from the Conservative minister comes as fears rise over the spread of the disease after Hong Kong confirmed its first death.
So far the virus has claimed 427 lives and more than 20,000 people worldwide have come down with the illness.
In Britain, there have been two confirmed cases, a University of York student and one of their relatives, who are being treated at the specialist infections disease unit at Newcastle's Royal Victoria Infirmary.
In a statement, Mr Raab said: “The safety and security of British people will always be our top priority.
“As such, we now advise British Nationals in China to leave the country if they can, to minimise their risk of exposure to the virus.
"Where there are still British Nationals in Hubei Province who wish to be evacuated, we will continue to work around the clock to facilitate this."
