Question to the HM Treasury:

To ask His Majesty's Government, further to the Written Answer by Baroness Anderson of Stoke-on-Trent on 23 December 2025 (HL12792), whether (1) Treasury ministers, or (2) their special advisers, had any involvement in media briefings prior to the Budget 2025 which were not issued alongside a Government press release or statement to Parliament.

The Treasury, its ministers, and special advisers place the utmost importance on budget security. A leak inquiry is currently underway, alongside a review of security processes to inform future fiscal events.

The Permanent Secretary to HM Treasury told the Treasury Select Committee on 10 December 2025 that he expects the review to conclude ahead of the Spring Statement on 3 March. The outcome of the review will be published.
