LUCY LETBY BOMBSHELL: THE MYSTERY DOCTOR KNOWN ONLY AS “DR A” HAS FINALLY BEEN NAMED

For years, the public knew him only as “Dr A.” Now, the mystery doctor at the center of one of the most closely watched parts of Lucy Letby’s trial has finally been identified.

Dr Mark Deakin, a consultant paediatrician who worked alongside Letby, has been named after the Court of Appeal lifted reporting restrictions that had protected his identity.

The decision came after Deakin’s death earlier this year, with judges ruling that the original reasons for keeping his identity secret no longer applied.

But his identity is only part of the story.

THE DOCTOR WHO BECAME CENTRAL TO THE CASE

During Letby’s trial, prosecutors described Deakin as a doctor with whom she had developed an unusually close relationship.

The prosecution suggested Letby had a “crush” on him and argued that some of the medical emergencies involving babies were connected to her desire to gain his attention.

Letby rejected that characterization.

She maintained that Deakin was simply a trusted friend and denied that they were romantically involved.

The evidence presented in court included more than 1,300 Facebook messages exchanged between the pair.

Handwritten notes discovered at Letby’s home also contained references to love and their relationship, adding another layer to the prosecution’s case.

THEN QUESTIONS FOLLOWED HIM TO ALDER HEY

The story did not end when Letby was convicted.

Deakin later worked at Alder Hey Children’s Hospital, where an investigation examined his relationship with Letby and his conduct after she had been removed from clinical duties at the Countess of Chester Hospital.

Among the issues investigated were arrangements that allowed Letby to make observational visits to Alder Hey in December 2016.

The investigation also examined Deakin’s handling of confidential patient information.

He was ultimately dismissed by Alder Hey for gross misconduct.

Deakin disputed aspects of the allegations and maintained that he had not understood the extent of the suspicions surrounding Letby when he arranged the visits.

HIS SUDDEN DEATH ADDED ANOTHER CHAPTER

In June 2026, just one day after being dismissed, Deakin was found unconscious inside his car at a retail park.

He was taken to intensive care but died nine days later.

An inquest is expected to examine the circumstances surrounding his death.

Importantly, there is currently no established evidence connecting Deakin’s death to the Letby case.

His death and the criminal proceedings against Letby are separate matters.

AND LETBY’S OWN CASE IS STILL DEVELOPING

The revelation comes as Letby’s wider legal battle continues.

She remains convicted and is serving whole-life sentences for the murder of seven babies and the attempted murder of seven others.

However, her legal team has submitted fresh material to the Criminal Cases Review Commission, which is reviewing her convictions.

The CCRC has made clear that its role is not to decide whether Letby is innocent or guilty. It can refer a case back to the courts if it concludes there is a real possibility that a conviction may not be upheld.

Meanwhile, the long-running Thirlwall Inquiry is examining what happened at the Countess of Chester Hospital, including how concerns about Letby were handled.

ONE NAME — AND MANY UNANSWERED QUESTIONS

For years, “Dr A” was a shadowy figure in the background of the Letby story.

Now his name is public.

Dr Mark Deakin.

His relationship with Letby, his decisions at Alder Hey, his dismissal and his unexpected death have all become part of a new chapter surrounding one of Britain’s most controversial criminal cases.

But the biggest legal question remains unchanged:

Will the new evidence being examined by the CCRC ultimately change the fate of Lucy Letby?

For now, her convictions remain in place.

And the mystery surrounding what really happened inside the neonatal unit — and how warnings were handled — continues to generate intense scrutiny.
