Prosecution position
The Inquiry was established on the basis that the convictions are sound, and its terms of reference expressly exclude re-evaluating them.
Expert challenge / post-conviction reading
Sir David Davis MP argued in the Commons on 16 July 2026 that those terms are too narrow. Health minister Preet Kaur Gill declined to widen them, telling the House that 'the point of the inquiry is not to rehearse Lucy Letby's trial; it is to focus on how people within the trust responded.'
What remains uncertain
Publication has slipped repeatedly — originally expected pre-March 2025, then Autumn 2025, then early 2026 — and on 13 May 2026 the Inquiry confirmed it will not publish until at least after Parliament's summer recess. Whenever it lands, it will not address whether the convictions are safe.
Common questions
What is in the Inquiry's scope?
How the Countess of Chester Hospital and its regulators responded to concerns about deaths on the unit. Re-evaluating the criminal convictions is expressly excluded.
When will the final report be published?
No date is fixed. On 13 May 2026 the Inquiry confirmed publication will not occur until at least after Parliament's summer recess — no earlier than September 2026, and the third successive delay.
Were the terms of reference widened after the July 2026 debate?
No. The Government declined to widen them in the Commons on 16 July 2026.
Will the report say whether the convictions are safe?
No. That is carved out of its remit. The CCRC is the only route by which the convictions can be re-examined.
