British Foreign Secretary Dominic Raab said on August 25 that almost all British citizens without dual nationality have been evacuated from Afghanistan.
"The lion share, almost of them who want to come out, have been brought home," Raab told Sky News.
He said in the last 24 hours some 2,000 people had been brought to Britain from Kabul, adding that London has been working with regional partners India and Pakistan.
Raab said that Britain would use every last remaining hour to bring its people back.
The Guardian newspaper reported late on August 24 that the last Royal Air Force aircraft evacuating people from Kabul could be in the next "24 to 36 hours."
"The military planners will work out how much time they need to withdraw their equipment, their staff, and what's really important is we will make the maximum use of all the time we have left," Raab said.
The Taliban has put an exit date of August 31 for all foreign evacuations.
Raab said Britain is pressing the permanent members of the UN Security Council to agree to "some parameters on the way forward" in dealing with Afghanistan under Taliban rule.
