A panel of international medical experts has given alternative causes of death in several cases against child serial killer Lucy Letby.
It comes as her defence lawyers announced they have asked for her case to be investigated as a miscarriage of justice.
Letby, 35, the UK’s most prolific child killer of modern times, is serving fifteen whole life terms in prison after she was convicted at Manchester Crown Court of murdering seven infants and attempting to murder seven others between June 2015 and June 2016.
Various methods were used to attack the babies while Letby worked as a nurse on the neonatal unit at the Countess of Chester Hospital.
One method was air being injected into the bloodstream which caused an air embolism, blocking the bloody supply and leading to sudden and unexpected collapses.
On Tuesday, retired neonatologist Dr Shoo Lee, who co-authored an academic paper on air embolisms (bubbles) in babies in 1989 which featured prominently during her trial, chaired a panel of 14 experts to compile an “impartial evidence-based report”.
Dr Lee said he believed his findings on skin mottling were misinterpreted by the prosecution. He said in a new paper he published in December 2024 that there were no cases of skin discolouration when air was injected into the veins.
At her trial in 2023, prosecutors pointed to skin discolouration in several of the victims as evidence that air had been injected into their veins by Letby.
“The notion that these cases are air embolism because they collapsed and because there were skin rashes has no basis in evidence. Let’s be clear about that,” Dr Lee said.

The panel laid out alternative causes of death in many of the cases, including natural causes and poor medical care at Countess of Chester Hospital.
“We did not find any murders,” Dr Lee said. “In all cases, death or injury were due to natural causes or just bad medical care.”
Asked about the Countess of Chester Hospital, Dr Lee, a retired medic from Canada, said: “I would say if this was a hospital in Canada, it would be shut down. It would not be happening.”
A spokesperson at the Countess of Chester Hospital NHS Foundation Trust said: “Due to the Thirlwall Inquiry and the ongoing police investigations, it would not be appropriate to comment further at this time.”
The Criminal Cases Review Commission (CCRC) will now review all the evidence after an application from the defence to determine if the case should be referred back to the courts.
A CCRC spokesperson said: “We are aware that there has been a great deal of speculation and commentary surrounding Lucy Letby’s case, much of it from parties with only a partial view of the evidence.
“We ask that everyone remembers the families affected by events at the Countess of Chester Hospital between June 2015 and June 2016.
“We have received a preliminary application in relation to Ms Letby’s case, and work has begun to assess the application.”
Opening the press conference, MP Sir David Davis described Letby’s convictions as “one of the major injustices of modern times”.
Findings will be earth-shattering for babies’ parents
This must have been one of the most distressing mornings for the grieving parents of the babies who died in Chester.
A 10-month trial concluded their new borns were murdered by Lucy Letby.
Now they have been presented with a body of evidence gathered by some of the world’s leading neonatal experts that could and probably will put some doubt against her conviction.
Every single baby’s death has been forensically analysed: the allegations presented in court with the circumstances of each death against what the panel claims are the clinical facts in the case.
Dr Shoo Lee, the panel chair, approached Letby’s lawyers following her conviction in 2023. He was convinced his 1989 paper on neonatal deaths used as evidence in the case against Letby had been misinterpreted.
The team he has assembled to examine each death is a world leader in their own respective field.
For parents learning today these experts believe some of the baby deaths were preventable and not the result of a serial killer nurse will come as nothing less than earth-shattering.
This expert panel review of each case, if true, could point to yet another systemic failure of NHS maternity care.
But now it will be for the Criminal Cases Review Commission to decide if Letby’s case is investigated as a potential miscarriage of justice.
Last year Letby lost two bids to challenge her convictions at the Court of Appeal – in May for seven murders and seven attempted murders, and in October for the attempted murder of a baby girl, which she was convicted of by a different jury at a retrial.
In December, the former nurse’s barrister, Mark McDonald, said he would seek permission from the Court of Appeal to re-open her case on the grounds Dr Dewi Evans, the lead prosecution medical expert at her trial, was “not reliable”.
Dr Evans, a retired consultant paediatrician, said concerns regarding his evidence were “unsubstantiated, unfounded, inaccurate”.
In September a public inquiry into how Letby was able to commit her crimes began hearing evidence. Closing legal submissions are expected in March and the findings are expected to be published this autumn.
Detectives from Cheshire Constabulary are also continuing their review of the care of some 4,000 babies admitted to the Countess of Chester Hospital from January 2012 to the end of June 2016, while Letby worked as a neonatal nurse, there. It also includes two work placements at Liverpool Women’s Hospital in 2012 and 2015.
Letby has been interviewed under caution at HMP Bronzefield in Ashford, Surrey, in relation to the ongoing investigation into baby deaths and non-fatal collapses.
Prince Harry and six other household names are suing the publishers of the Daily Mail newspaper over alleged unlawful information gathering dating back 30 years.
The case has been ongoing since 2022 and is just one of several Harry has filed against media organisations since 2019 over alleged breaches of privacy, unlawful practices and false stories.
Associated Newspapers (ANL) – which also publishes The Mail on Sunday and MailOnline – strongly denies any wrongdoing.
A full trial is not expected to start at London’s High Court until January, but a pre-trial hearing, which helps manage the case and resolve any outstanding issues, is set to take place today.
Here is everything you need to know about the case.
What’s alleged?
The alleged unlawful acts are said to have taken place from 1993 to 2011, including the publisher hiring private investigators to secretly place listening devices inside cars and homes and paying police officials for inside information.
When bringing the lawsuit in 2022, lawyers for the claimants said they had become aware of “highly distressing” evidence revealing they had been victims of “abhorrent criminal activity” and “gross breaches of privacy” by Associated Newspapers.
Associated Newspapers denies the allegations, describing them as “preposterous smears”, and claims the legal action is “a fishing expedition by [the] claimants and their lawyers”.
The accusations include:
• The hiring of private investigators to secretly place listening devices inside people’s cars and homes;
• The commissioning of individuals to surreptitiously listen into and record people’s live, private telephone calls while they were taking place;
• The payment of police officials, with corrupt links to private investigators, for inside, sensitive information;
• The impersonation of individuals to obtain medical information from private hospitals, clinics, and treatment centres by deception;
• The accessing of bank accounts, credit histories and financial transactions through illicit means and manipulation.

Who else is involved?
While Prince Harry is one of the key players, as a group litigation, he is not the only claimant.
The others include:
• Actress Elizabeth Hurley • Actress Sadie Frost • Sir Elton John and his husband, filmmaker David Furnish • Baroness Doreen Lawrence, mother of Stephen Lawrence • Former Liberal Democrat politician Sir Simon Hughes

They all allege they have been victims of “abhorrent criminal activity” and “gross breaches of privacy” by ANL.

What happened in 2023?
During a preliminary hearing in March 2023, Judge Matthew Nicklin was tasked with ruling whether the case can proceed to trial.
ANL had asked for the case to be struck out entirely, arguing the legal challenges against it were brought “far too late”, but David Sherborne called for the publisher’s application to be dismissed.
Lawyers for the publishers said the claims fell outside the statute of limitations – a law indicating that privacy claims should be brought with six years – and the claimants should have known, or could have found out, they had a potential case before October 2016.

They also argued some aspects of the cases should be thrown out as they breach orders made by Lord Justice Leveson as part of his 2011 inquiry into media standards.
During the hearing, a number of the claimants attended the High Court, including Prince Harry, to the surprise of the British media.
Witness statements from all seven claimants were also released. The duke’s statement said he is bringing the claim “because I love my country” and remains “deeply concerned” by the “unchecked power, influence and criminality” of the publisher.
“If the most influential newspaper company can successfully evade justice, then in my opinion the whole country is doomed,” he said.
On 10 November 2023, Mr Justice Nicklin gave the go-ahead for the case to go to trial, saying ANL had “not been able to deliver a ‘knockout blow’ to the claims of any of these claimants”.
What’s happened since?
Earlier this year, lawyers for the claimants sought to amend their case to add a swathe of new allegations for the trial.
They argued that they should be allowed to rely on evidence that they said showed the Mail was involved in targeting Kate, the Princess of Wales.
However, Mr Justice Nicklin ruled this allegation was brought too late before trial.
In a further development in November, the High Court heard that a key witness in the case, private investigator Gavin Burrows, claimed his signature on a statement confirming alleged hacking had taken place, was forged.

In the statement from 2021, Mr Burrows allegedly claimed to have hacked voicemails, tapped landlines, and accessed financial and medical information at the request of a journalist at the Mail On Sunday.
The statement was important, as five of the seven claimants involved in the case told the court they embarked on legal action against ANL based on evidence apparently obtained by Mr Burrows.
Mr Burrows previously retracted his statement in 2023, but the court heard he reiterated the denial to ANL’s lawyers in September this year.
It is now up to the claimant’s lawyer Mr Sherborne to decide if he still wants to call Mr Burrows as a witness for the trial.
Mr Justice Nicklin previously said if Mr Burrows gave evidence that was inconsistent with the evidence they had obtained, then he could apply to treat him as “hostile”.
Could the case end before going to trial?
In short, yes.
During pre-trial reviews, cases can either be settled or dismissed from court in both civil and criminal cases, meaning no trial will take place.
This happened in Harry’s case against News Group Newspapers (NGN), which publishes The Sun. The duke made similar accusations about NGN, which involved unlawful information gathering by journalists and private investigators.
Before an up-to 10-week trial began earlier this year, it was announced both sides had “reached an agreement” and that NGN had offered an apology to Harry and would pay “substantial damages”.
The settlement was reported to be worth more than £10m, mostly in legal fees.
Another of Harry’s legal cases, this time against Mirror Group Newspapers (MGN) over accusations of historical phone hacking, did go to trial.
The trial saw Harry take to the witness box, making him the first senior royal to give evidence in a courtroom since the 19th century.
In December 2023, the Honourable Mr Justice Fancourt concluded that the duke’s phone had been hacked “to a modest extent” between 2003 and 2009, and 15 of 33 articles he complained about were the product of unlawful techniques.
Bereaved families of black, minorities and migrant women who died after suffering violence and abuse have called on the prime minister to help end femicide.
At a Downing Street vigil on International Day for the Elimination of Violence Against Women, the group said urgent reforms to policing and sentencing are needed “to address systemic failures”.
Yasmin Javed, whose daughter Fawziyah Javed was killed after being pushed by her husband from Arthur’s Seat in Edinburgh, said authorities had ignored Fawziyah’s reports of abuse.

“It fell on deaf ears,” she told Sky News, explaining that Fawziyah, 31, who was pregnant when she died, had made complaints about her husband but had been murdered days before she was set to leave him.
“We’ve had our hearts ripped into millions of pieces. It’s not getting any easier, it’s getting more and more difficult.”
Tuesday’s vigil highlighted key legislative amendments the families, led by campaign group Southall Black Sisters, are championing.
The amendments include Banaz’s Law, named after 20-year-old Banaz Mahmod, who was subjected to an horrific assault, strangled and stuffed in a suitcase by family members on the orders of her father.

The amendment seeks to explicitly recognise “honour-based” abuse as an aggravating factor in sentencing for relevant offences.
The families also want courts to impose sentences equivalent to murder for self-harm and suicides driven by domestic and “honour”-based abuse, and say the government must ensure all women have equal access to safety and support, regardless of immigration status.
Banaz Mahmod’s sister Bekhal, who testified against her relatives to help secure their conviction, said nearly two decades after the murder, efforts to protect women had not progressed.

Speaking from an undisclosed location in the witness protection scheme, she said the murder “happened in 2006, and we’re almost in 2026 – that’s 20 years later. Not much has changed and it’s very, very disappointing.
“What happened to Banaz has happened, but what we could do is prevent it from happening to other people. I don’t understand why much more hasn’t been done to better the situation for others.”
A man charged with the murder of two women within five months of each other, and the rape of a third, has appeared in court.
Appearing at the Old Bailey via videolink on Wednesday, Simon Levy only spoke to confirm his name and was not asked to enter a plea to any of the charges.
Levy, 40, of Beaufoy Road, Tottenham, was charged in September with the murder of 39-year-old Sheryl Wilkins in Tottenham, north London, on 24 August.
While in custody, he was also charged with the murder of Carmenza Valencia-Trujillo, from Colombia, who died on the Aylesbury Estate, southeast London, in March.

Prosecutor Tom Little KC told the court that Ms Valencia-Trujillo was found in a block of flats that is “very largely disused” with few residents or passers-by except security guards.
He said: “The body of the deceased was found in the early evening of 17 March 2025 in a block of flats very largely disused, so it does not contain many residents nor many people passing by apart from the odd security officer who patrol the area for safety.”
It is alleged that he travelled to the area the day before and that he killed her during the course of a sexual encounter.

Levy was also accused of grievous bodily harm with intent, non-fatal strangulation and two counts of rape against a third woman, who cannot be named for legal reasons, in Haringey, north London, on 21 January, police said.
The Met Police said on Monday that all three cases are now being treated as part of a single, joined investigation and a trial date has been set for June 2026 at the Old Bailey.
