Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government whether they will publish the letter sent by Lord Vallance of Balham to the Home Secretary following his meeting with the CEO of MBR Acres on 17 September 2025.

The Department for Science, Innovation and Technology will not be publishing this letter. Releasing internal correspondence at this stage would prematurely expose discussions that relate to the ongoing development of the government’s position on a sensitive policy area. The issues involve complex regulatory, scientific, and public safety considerations, and ministerial discussions include exploratory thinking, provisional advice, and options that have not yet been finalised.
