"We have taken out 2,000 people in the last 24 hours and 10,000 since April," UK Defence Secretary Ben Wallace tells the BBC.

"Our focus is to get as many people out."

"But the scale of the challenge means that not everyone will get out. We are ruthlessly prioritising people."

"We want to stay longer [than 31 August] if it is possible to do so. The two people with the biggest vote in the room are the US... and the Taliban.

"[The Taliban] could make life incredibly difficult. It will be a discussion between the US government and the Taliban."

"If America makes a decision that it doesn't want to extend, then we will be out by 31 August."
