Andy Burnham has said the prime minister told him the UK government believes Iran was involved in a recent incident at RAF Fairford.
Burnham made the remarks after the suspects connected to the case were released on what has been described as "the strictest possible bail conditions" just days earlier. He did not provide additional operational detail, and the prime minister's office has not publicly expanded on the assertion.
The matter remains under active scrutiny by authorities. Officials have not set out a full public account of how the conclusion on Iran's involvement was reached, and there has been no official attribution set out in detail to date.
Calls for further clarification have been made by political figures and stakeholders, who say the public and Parliament should be given fuller information about the evidence and the steps being taken. The government has signalled it will provide updates as investigations progress and as any intelligence assessments can be responsibly disclosed.
