Core Event
Consultant Mark Deakin, a diabetes specialist at Alder Hey Children’s Hospital, had his court-imposed anonymity removed after his death. The Court of Appeal ruled the order, first applied during Lucy Letby’s murder trial, was no longer needed. Deakin was dismissed for gross misconduct after a disciplinary panel found he breached patient confidentiality by exchanging over 1,300 Facebook messages with Letby and arranging “observational visits” for her at Alder Hey despite concerns about her involvement in neonatal deaths. He collapsed in his car in early June, was hospitalized, and died on July 3 at Whiston Hospital, Merseyside.
Background & Context
Lucy Letby, a former neonatal nurse at the Countess of Chester Hospital, was convicted in August 2023 of murdering seven babies and attempting to murder seven more. During her trial, Deakin gave evidence behind a screen, describing emergency calls and resuscitations he and Letby had jointly handled. Their text-message exchange, shown to the jury, included personal references such as Letby calling Deakin “sweetie” and “love.”
In June 2024, Deakin faced a three-day disciplinary hearing for breaching confidentiality concerning a premature baby with haemophilia (“Baby N”). He admitted the breach but denied knowing Letby was under suspicion when he organised her visits. The panel rejected his explanation and terminated his employment on June 23.
Official Statements & Responses
Lady Justice Thirlwall, chair of the public inquiry into Letby’s crimes, heard Deakin’s testimony in October 2024, during which he said Letby had “misled and maybe manipulated” him into providing information about vulnerable infants.
Baby N’s mother, testifying at the inquiry, accused Deakin of “blatantly” breaching her son’s confidentiality and said she had lodged a formal complaint with Alder Hey.
Data & Statistics
- Over 1,300 Facebook messages exchanged between Deakin and Letby from June to September 2016.
- Deakin was dismissed on June 23 and died on July 3.
On-the-Ground Reports
Relatives reported Deakin missing the day after his dismissal; he was found collapsed in an apparent diabetic coma in his car at a retail park about 20 miles from his Cheshire home. He was admitted to intensive care but never regained consciousness. The Cheshire Coroner has opened “preliminary inquiries” into his death, noting that no note was found beside his body.
Conflicting Reports & Gaps
The inquiry has not released a definitive cause of death beyond the initial description of a diabetic coma, and the coroner’s final findings remain pending. Details of any formal regulatory action by the General Medical Council have not been disclosed.

What’s Next
The public inquiry, overseen by Lady Justice Thirlwall, is scheduled to report later this year, addressing Deakin’s role in the Letby case, hospital oversight, and the implications of his breach of patient confidentiality. The coroner’s investigation into his death is also ongoing.
