Recommendations (1)
Establish standing public body to administer future redress schemes
- The Department for Business and Trade acknowledged this recommendation on 9 October 2025, stating it saw "clear advantages" but that options needed careful consideration, with a substantive statement expected by summer 2026 (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted the government had not committed to establishing a standing public body as recommended (Business and Trade Select Committee evidence session, January 2026).
- The Business and Trade Committee report HC 1598 found no progress on establishing the body, with the government having promised a substantive statement by summer 2026 (Business and Trade Committee, HC 1598, March 2026).
