BORIS Johnson has refused to accept America’s “false deadline” for pulling out of Afghanistan.
The PM insists he will keep a presence for as long as it takes to get people out of the war-torn country.
US President Joe Biden has promised the military mission will end on August 31.
But a senior government source said: “The situation is in flux. It would be unwise to impose a deadline.
“Our priority is getting our people out safely and quickly.”
Mr Johnson told United Nations boss Antonio Guterres yesterday that the organisation should lead the humanitarian effort.
Downing Street said the PM also believes Nato and G7 leaders have a role to play.
He has proposed a meeting this week to President Biden and other leaders to work on an immediate and long-term response to the crisis.
A source said: “The PM has been on the phone to world leaders every day coordinating international action.”
