A Ministry of Defence spokesperson said: “We do not routinely comment on the activity of other nations. Aircraft and other assets move regularly according to operational requirements.”
It comes weeks after an Iran-linked security incident at RAF Fairford, which saw the U.S. pull its bombers out of the base and return them to America.
A major incident was declared after three suspicious vans were seen near Fairford, which led to eight arrests. Two British nationals appeared in court in October in connection with an alleged plot connected to Iran.
U.K. Prime Minister Andy Burnham’s spokesman said: “The U.S. is one of our top security partners. We’re in constant communication with them, sharing intelligence and accessing threats together. Aircraft and other assets move regularly according to operational requirements… The protection of our bases, both in the U.K. and across the world, is a top priority.”
Conservative Party Leader Kemi Badenoch said on Tuesday that the latest U.S. withdrawal of assets is “very concerning, and our government’s got absolutely nothing to say about it.”
Head of the MI5 intelligence service Ken McCallum said last month that threats from foreign adversaries against the U.K. had quadrupled in the last decade, including an increase in Iran-sponsored aggression against Jewish sites and military bases.
