A Christian barrister says the chaos brought about over the transfer of power in Afghanistan last year was the fault of the US.
Paul Diamond has been speaking following a claim by a group of MPs that "serious systemic failures" during last year's Afghanistan evacuation by the Foreign Office lowered the UK's global standing.
The inquiry by the Foreign Affairs Committee found the UK's withdrawal from the country to be a "disaster" while Afghan allies and British soldiers were "utterly let down by deep failures of leadership".
Chairman Tom Tugendhat said there had been a failure to lead "at a time when lives were quite literally being lost."
Diamond, who is a leading barrister on law of religious liberty; including matters of both ethical and social conscience suggests blaming the UK government isn't totally fair and instead the finger should be pointed at the US.
"The withdrawal from Afghanistan was a total disaster and I believe tens, if not hundreds of thousands of people's lives were lost.
"Many people had to flee and many people were abandoned, and much of the Civil Service went over to the Taliban.
"My clear blame is on President Biden. He was in the country with the greatest forces there.
"I would imagine it's fairly unrealistic to expect the British military command to counteract or act without American authorization at most levels.
"So if there was a failure, it was a failure from the United States not to have an ordered retreat with a failure by the United States not to talk with their allies and clearly was a crisis situation developing.
"We didn't have any plans to protect the most vulnerable, but I still believe President Biden must take the call on this."
Diamond claims it was extraordinary that he appeared to be pushing for withdrawal on the 20th anniversary from the 11th of September 2001 to 2021 - a move he claims was politically motivated.
Speaking of Biden, he said: "He just shrugged his shoulders at all the deaths.
"I mean, I was in contact with many Christians in Kabul, they were absolutely desperate.
"They had to be got out the country and a colleague of mine was on the phone with somebody, and they heard the shots in the house, so it was utter chaos.
"It was badly administered by the British, but I think the primary blame must fall on the United States."
Joe Biden has defended his handling of the situation. Speaking in September last year, he said: "I was not going to extend this forever war, and I was not extending a forever exit," adding: "The war in Afghanistan is now over."
