Summary based on third-party reviews and Channel 5 listing material. This site does not host the documentary or a transcript.
Lucy Letby: The New Evidence is the Channel 5 follow-up to Lucy Letby: Did She Really Do It? (broadcast 6 October 2024). It revisits the conviction-safety question after the post-conviction expert evidence had accumulated further, and treats the medical and statistical critique with the seriousness consistent with mainstream British investigative documentary. UK viewers can find the programme on the My5 catch-up service; access outside the UK is geo-restricted.
The Sheffield DocFest 2025 panel summary describes the two Channel 5 documentaries together as the body of work in which a UK terrestrial broadcaster “uncovered key evidence and shaped legal proceedings”. As with the first film, the documentary works through the trial evidence and features named medical, scientific and legal contributors who have publicly questioned the safety of the convictions. The case for a team of international scientists having concluded that the Crown’s case does not stand up to scrutiny is consistent with the public position of the fourteen-member Shoo Lee International Expert Panel that reported on 3 February 2025; the documentary appears to draw on that wider expert record without itself being the Panel report.
As a piece of British public-record media engagement, the two Channel 5 films sit in the same procedural arc as the May 2024 New Yorker Rachel Aviv piece, the February 2025 Shoo Lee Panel report, and the February 2026 Netflix release — collectively, the body of mainstream long-form engagement that has built up around the post-conviction expert critique. Together with Did She Really Do It?, this film is the first British television engagement with the Shoo Lee Panel findings.
The Sheffield DocFest 2025 panel discussion treated the pair of Channel 5 films as a documentary-industry indicator: that a free-to-air UK broadcaster commissioned and aired a second instalment on the case — rather than treating the first film’s critical reception as a reason not to return — is itself a signal about how UK commissioning editors weigh the conviction-safety question. The follow-up structure allowed the production to update viewers on the accumulating expert record (the May 2025 Joint Insulin Report, the June 2025 Panel Additional-10 report, the October 2025 CCRC supplementary submissions) that had emerged between the first film’s October 2024 air-date and the follow-up’s broadcast.
