British nationals in Sudan have 24 hours to catch a flight before they are stopped, the deputy prime minister has said.

The flights will stop at 6pm UK time on Saturday, Oliver Dowden confirmed.

Speaking to reporters on Friday afternoon, he said more than 1,500 people had now been flown out of the country.

But he said there had been a “significant decline in British nationals coming forward”, so the government would cease the flights.

Asked if that would mean abandoning British nationals who haven’t been able to make it in time, Mr Dowden rejected the claim.

He said: “Every single British national that has come forward and their eligible dependents has been put safely onto a plane.

“We are seeing those numbers declining significantly. And just like other countries, as those numbers decline, we have put an end date on this.

“What I would say is that even beyond that, we will maintain consular support in Sudan, particularly at the exit route. So both to the north, to south and particularly Port Sudan itself.”

Asked what his advice would be for those left behind, Mr Dowden said: “Well, first of all, we have been very clear that this would be a time limited operation.

“We gave a very clear signal over 24 hours ago that people should expect that as the ceasefire comes to an end, we would be winding down the number of flights.

“We are now saying to those people, you have another 24 hours if you are eligible to make your way to the airport and we will get you on a plane, just as we have done for every other person that has come forward who is eligible, making it the longest and largest evacuation effort of any Western country.”
