MP tracker
A running list of UK MPs, Peers and senior silks who have publicly questioned the safety of the Letby convictions. Updated as new interventions are made. Each entry links to the public source (Hansard, broadsheet op-ed, press statement) where available. If you are considering writing to your MP, this page tells you who has already engaged and in what context.

Why this page exists
The ‘email your MP’ action on this site is meaningful only if readers can see that the question is already live in Parliament. The Sir David Davis adjournment debate of 5 November 2024 was the first formal Parliamentary engagement; subsequent interventions by Lord Sumption and Baroness Helena Kennedy KC extend the question into the House of Lords and the senior Bar. This page lets readers see the current state of Parliamentary and senior-legal engagement before composing their own letter.

Not in Parliament, but relevant to the legal architecture:
- Bar Council letter in The Times (April 2025) — collective senior-Bar intervention on the expert-evidence standards raised by the case.
- Mark McDonald KC — defence counsel leading the CCRC application (see biography).
- Rob Rinder KC — public legal-audience commentary (September 2024 intervention marked the broadening from specialist to legal-mainstream).
