British nationals unable to return home due to the coronavirus pandemic are in a “dire” situation, a former cabinet minister has warned.
Tory MP Caroline Nokes said many were stranded as countries closed their borders and airlines cancelled flights.
The government’s call for people to return home as quickly as possible were like “empty words” to them, she added.
Foreign Secretary Dominic Raab said his staff were working with other nations and airlines to “overcome barriers”.
Responding to an urgent question in Parliament, Mr Raab said the situation was being exacerbated by countries closing their borders “with no or little notice”.
With the pandemic worsening across much of the world, the Foreign Office changed its travel advice on Sunday urging British nationals to return home as soon as possible.
Mr Raab said officials were working “night and day” with other governments and airlines to put urgent arrangements into place.
But Ms Nokes, the MP for Romney and Southampton North, said many of her constituents were not able to get through to embassy staff on the phone and had received standard e-mail messages telling them to contact their tour operator or insurer.
Many found themselves hundred of miles from airports, with hotel accommodation becoming increasingly scarce.
BBC viewer Chas Parker said his 18-year old son Ben had been v in Phnom Penh, Cambodia because he didn’t have an appointment.
He said Ben was given a card by security officers outside the building but when he e-mailed the consulate, he got a “bog standard” response.
Mr Parker said he feared for his son’s safety amid an increasingly hostile atmosphere and rumours that he and other foreign nationals could be put into quarantine.
While he had since managed to book a seat for his son on a flight home via South Korea, Mr Parker said the whole process had been tough.
Commercial flights from many destinations were simply not available, she said, unless they were “priced at tens of thousands of pounds and routed via airports expected to close imminently”.
“Hotels are closing, flights are cancelled, borders are closing and there are no routes home.
“He (Mr Raab) knows the situation is dire – but he knew that last week when he said in the House that we will look and liaise with the airline operators to make sure where there are gaps we can always provide as much support as possible.”
“I ask him to explain how he is working with airlines with unused planes parked at airports around the globe to bring our people home… the vision of British citizens sleeping on the streets of Caracas is not a good one.”
Mr Raab said the rate of border closures and travel disruption was “unprecedented” in modern times and he had doubled the number of consular staff to deal with the “surge in demand”.
He said the UK was addressing specific problems facing British nationals in Peru, Singapore, Australia and New Zealand, working with their governments and airlines to keep routes going, and to re-open those that had closed.
Mr Raab told MPs that special flights will be laid on later this week to bring Britons back from Peru, while the UK had agreed with Singapore that it will act as a transit hub to help those trying to get back from Australia and New Zealand.
“Our overriding priority now is to assist the thousands of British travellers who need and want to return home,” he told MPs.
“Where commercial options are not possible or limited by domestic restrictions we are in close contact with airlines and local authorities in those countries to overcome those barriers.”
