Britain has evacuated more than 2,000 Afghans since the Taliban takeover, Prime Minister Boris Johnson told lawmakers on Wednesday, as parliament was recalled to discuss the crisis.

"We have so far secured the safe return of 306 UK nationals and 2,052 Afghan nationals as part of our resettlement programme," he said, adding that 2,000 more Afghan applications were complete, and "many more" being processed.
