LUCY LETBY CASE: NEW INQUIRY REVEALS MAJOR HOSPITAL FAILURES AS HER CONVICTIONS REMAIN UNDER REVIEW

A major new report into the Lucy Letby case has exposed serious failures at the hospital where the former neonatal nurse worked, while her legal team continues to challenge her convictions.

The Thirlwall Inquiry, established to examine events at the Countess of Chester Hospital between 2015 and 2018, published its long-awaited final report on September 15, 2026.

The inquiry found what its chair, Lady Justice Kathryn Thirlwall, described as dysfunctional management and governance, a major divide between hospital leaders and clinicians, and a failure to properly understand safeguarding responsibilities.

The report also concluded that some opportunities to protect babies were missed because concerns about Letby were not acted upon quickly enough.

SERIOUS CONCERNS WERE NOT ESCALATED

Letby worked as a neonatal nurse at the Countess of Chester Hospital during the period examined by the inquiry.

Concerns about unusual collapses and deaths among babies were raised by medical staff, but the inquiry found that the hospital did not respond appropriately once suspicions began to emerge.

According to the inquiry, staff continued looking for clinical explanations for what was happening when safeguarding procedures should also have been considered once there was suspicion that a member of staff might be deliberately causing harm.

The report criticized the hospital’s leadership for failing to create an environment in which concerns could be properly escalated and investigated.

It also found failures in communication between senior management and clinicians, contributing to delays in taking decisive action.

LETBY REMAINS CONVICTED

The inquiry did not determine whether Lucy Letby’s convictions were correct or incorrect.

Letby was convicted in 2023 of murdering seven babies and attempting to murder six others. A later retrial resulted in another attempted-murder conviction, bringing the total number of attempted-murder convictions to seven. She is serving whole-life sentences and continues to maintain her innocence.

Her first attempt to appeal her convictions was rejected by the Court of Appeal in 2024.

However, her case is now being reviewed by the Criminal Cases Review Commission (CCRC) following an application supported by new material and expert evidence. The CCRC has stressed that its role is not to decide guilt or innocence, but to determine whether a case should potentially be referred back to the appellate courts.

QUESTIONS AROUND THE MEDICAL EVIDENCE

The legal debate surrounding Letby’s convictions has intensified in recent years, with members of her defense team presenting arguments challenging aspects of the medical evidence used during her trials.

But the scientific debate has also become complicated.

Two experts who had been involved with Letby’s defense team recently withdrew, saying they could not support certain arguments that they considered inconsistent with available evidence, established science and physiology.

Their withdrawal does not itself determine the validity of Letby’s convictions or the broader defense case.

The CCRC’s review remains ongoing.

WHAT HAPPENS NEXT?

The publication of the Thirlwall report does not automatically reopen Letby’s convictions.

Instead, two separate issues continue in parallel: the inquiry’s findings about how the hospital responded to concerns, and the legal process examining whether there are grounds to challenge the convictions.

The CCRC has said it will make an impartial, evidence-based assessment and will refer a case to the Court of Appeal only if the legal test is met.

For the families of the babies involved, the inquiry has also brought renewed attention to the institutional failures surrounding the events.

For Letby, the convictions remain in place.

And as the CCRC continues its review, the legal questions surrounding her case remain unresolved.
