To ask the Secretary of State for Defence, pursuant to the Answer of 27 January 2026 to Question 106994 on Veterans: Radiation Exposure, whether research on the effects of radiation on British servicemen held by the Technical Cooperation Programme of the Ministry of Defence is held in (a) this country and (b) another country; and by what body it is held.

Further to the answer provided to Question 106994, and recognising the gravity of this issue, the Department has been working to identify teams and bodies who may have, or may have had, an interest in this work. This may include entities which are now arms-length bodies.

As may be expected, the historical nature of these events is making it more challenging to locate, access and search information held in a variety of archives, both electronic and paper. In particular, it is unclear if records and archives relating to particular programmes or events include any material specifically relating to British Service personnel.

Officials are developing a more substantive overview of the situation. This will be included in the letter which was promised to Emma Lewell MP in response to Question 106994, and which will be copied to the hon. Member.
