It's widely accepted that the late republican Freddie Scappaticci was the agent, codenamed "Stakeknife".
He headed the IRA's so-called "nutting squad", a notorious internal security unit tasked with hunting and executing informants, but was himself operating as a mole for British intelligence.
The final report of a seven-year investigation named Operation Kenova has found that "there is a compelling ethical case" to reveal the agent's identity.
Operation Kenova live: 'Stakeknife' spy inside IRA committed 'worst possible' crimes
Head of Kenova Sir Iain Livingstone said that "it is in the public interest that Stakeknife is named". He urged the government to depart from its "neither confirm nor deny" (NCND) policy on the grounds of public interest.
It's understood that the government believes Stakeknife cannot be officially named at this time due to some outstanding legal issues. Sky News has approached No 10 Downing Street for comment.
Freddie Scappaticci died two years ago denying that he was the agent, but all sides in Northern Ireland accept his denial was false.
The report also found a "significant failure" by MI5 in its late provision of materials to the investigation. "The further material revealed MI5 had earlier and greater knowledge of the agent than previously stated," the report says.
Sir Ian Livingstone added that "further investigative opportunities were undoubtedly lost", and that the confidence of the communities in Northern Ireland was undermined. Sky News has approached the security agency for comment.
Stakeknife produced a "vast" amount of intelligence. 3,517 reports from the agent were discovered, including 377 from one 18-month period. But the report found the intelligence was not shared with those who could have used it to save lives.

Last year, Operation Kenova's interim report found the security forces were frequently aware of imminent abductions and murders but failed to protect those at risk.
Today's report found his army handlers even took Stakeknife out of Northern Ireland for two holidays, at a time when he was sought by police for murder and kidnapping. He was flown on military aircraft and given military ID.
As a result, preventable deaths occurred with the security forces' knowledge and those responsible were not brought to justice and were instead left free to reoffend.
'Wholly unjustified criminality'
The 2024 report also concluded that Stakeknife was involved in "very serious and wholly unjustifiable criminality", including murder, and claims his intelligence saved "countless" or "hundreds" of lives were exaggerated. It found that the number of lives saved by his spying ranged from the high single figures to low double figures.
This contradicted claims that Scappaticci had saved hundreds of lives during the years he was active, with a former defence chief describing him as "the goose that laid the golden eggs". The interim report found that claim to be "inherently implausible" and "a comparison rooted in fables and fairy tales".
The 2024 report also called on the UK government to apologise to bereaved families, given that many murders were avoidable.
'Each evil act being the epitome of cowardice'
There was also a call for an apology from republican leaders for "the most shameful and evil" actions of the Provisional IRA (PIRA). "It was PIRA that committed the brutal acts of torture and murder, each evil act being the epitome of cowardice," the report stated.
No prosecutions connected with Stakeknife will take place, prosecutors in Northern Ireland have already decided.
Families of IRA victims associated with Stakeknife will give their response to the Kenova report in a news conference later today.
They want Scappaticci to be officially named, and many are seeking an apology from the British government.
An investigation into NHS maternity services is under way after a series of shocking scandals.
The National Maternity and Neonatal Investigation (NMNI) is being led by Baroness Amos, who said "nothing prepared her" for the amount of "unacceptable care" families currently receive.
A report has been released documenting her initial reflections and impressions after meeting families and visiting hospitals.
She will investigate 12 NHS trusts in total, including Oxford University Hospitals (OUH), which runs the world-renowned John Radcliffe Hospital.
'I was left in my own blood'
Rebecca Matthews formed a campaign for families failed by OUH after her own traumatic births.
Asked to discuss the care she received, she said she "could only describe it as callous".
"There wasn't any kindness there. I was left in my own blood," she added.
Ms Matthews recently took part in evidence-gathering sessions held by Baroness Amos.
But when she read her interim report, she said it was "disappointing", as it appeared to be "a bullet point list of failings that actually we've seen time and time again in independent reviews".
"The reflections don't mention accountability at all," she said.

'Why are we struggling to provide?'
Based on her initial inquiries, Baroness Amos found common themes, including women not being listened to and being "disregarded" when they raised concerns.
Many weren't given the right information to make informed choices about their care.
She was told of discrimination against women of colour, working-class mothers, or parents who were younger.
A "staggering" 748 recommendations have been made about NHS maternity services in recent years, Baroness Amos revealed - and she does "not understand why change has been so slow".
She asked: "Why are we in England still struggling to provide safe, reliable maternity and neonatal care everywhere in the country?"
Baroness Amos told Sky News' Mornings with Ridge and Frost: "I have been shocked…I've been shocked because there have been so many reviews before."
She said she had been asked to come up with "clear national recommendations that will stop this and will make a difference".
"It just cannot continue, there's too much harm, too much distress, too much trauma," Baroness Amos said, describing the long-term consequences for families as "almost unbearable".
Asked if there was "systematic racism in the NHS", she said there was "clearly discrimination".
"When a woman tells you that she is making choices that she knows may be detrimental to her because of her previous experience of healthcare, because of the racism that she has experienced, there is something additive here in terms of race," she said.
"Inequalities is a key strand of the work that we're doing."
The most recent health watchdog findings paint a depressing picture of maternity services.
Almost two-thirds of acute hospital maternity services were judged either inadequate or required improvement for safety.

This investigation is not due to report back fully until the spring.
But some campaigners are already worried it won't bring meaningful change to maternity services.
Ms Matthews said it "seems as though it's heading the same way that other reviews have gone in the past, leading to some recommendations but no teeth".
"We need some mechanisms that are going to hold people and systems to account," she said.
'More to do'
OUH chief nurse Yvonne Christley said in a statement that "feedback received from patients using our maternity service over the last year is positive overall".
"However, we know we have more to do to improve our maternity services," she added.
"Our present focus is on listening to the experiences of women and families, which is helping us to identify opportunities for improvement."

The bodies of a man, 35, a woman, 55, and another person, about whom no information was given, were recovered after a major rescue operation using jet skis and helicopters on Sunday.
A woman, the fourth victim, died on Monday, a day after she had been revived at the scene and airlifted to hospital.
The victims have not yet been named.
The pool is located at Isla Cangrejo, on Tenerife's Los Gigantes coast, and is popular with foreign holidaymakers.

It is bordered by volcanic rock on one side and cemented off from the sea on the other.
But it can be very dangerous during rough seas when large waves can easily overcome the cement barrier.
'We ask people to pay attention'
A weather advisory for rough seas was in effect at the time the swimmers were swept away, local media reports.
One outlet had reported that the pool had been closed to swimmers since 3 December.
Emilio Navarro, the mayor of Santiago Del Tiede, said: "We ask people to pay attention to the signage put up by the authorities. It's to take care of and protect everyone."
Last month, three people were killed and 15 injured in Tenerife after a tidal surge during treacherous weather.
Steven Hutton, 43, was hit with a hammer and stabbed in the heart during a late-night home invasion at his flat in Dundee in March 2024.
He was taken to the city's Ninewells Hospital, but died the following day.
Brian Miller, 29, Scott Henderson, 40, Barry Murray, 45, and Carri Stewart, 44, were on Monday found guilty of murder following a trial at the High Court in Glasgow.
The killers were each handed a life sentence, and will spend at least two decades behind bars.
In her sentencing statement, Judge Lady Haldane said the evidence provided a "compelling picture of a plan to inflict serious violence upon Mr Hutton in his own home".
The judge described it as a "frenzied assault", which in part was sparked due to a "missing packet of Pregabalin medication".
'Callous' behaviour
Lady Haldane stated: "Steven Hutton lost his life in these horrific circumstances, compounded by the fact that not one of you sought to seek assistance for him as he lay dying until you were all well clear of the property.
"That is behaviour that can only be described as callous."

The judge paid tribute to Mr Hutton's family and friends.
She added: "Those close to Mr Hutton, in particular his mother, have attended faithfully every day of this trial, and their quiet dignity throughout what must have been at times harrowing and distressing evidence stands in stark contrast to your behaviour.
"Mrs Hutton has in addition provided a detailed and moving account of her relationship with Mr Hutton, her only son, and the impact his loss has had upon her.
"I thank her for taking the time to prepare this thoughtful document, and I have taken all that she has said into account."
Detective Inspector Richard Baird said the killers "now face the consequences of their actions".
He added: "This was an unprovoked attack that cost Steven Hutton his life. We hope this conviction brings some form of comfort to Steven's family."
Iain Packer murdered Emma Caldwell, 27, in 2005.
In February 2024, he was ordered to serve a minimum of 36 years behind bars after being convicted of a string of violent offences.
Alongside double-murderer Andrew Innes, it is the second longest sentence ever handed down by a Scottish court, behind the 37-year minimum jail term given to World's End killer Angus Sinclair in 2014.
Packer was found guilty of 33 offences following a trial at the High Court in Glasgow, including Ms Caldwell's murder, 11 rapes and multiple sexual assaults against other women.
Following the killer's conviction, Sky News heard testimony from several former sex workers who raised concerns to police about his dangerous sexual behaviour years before Ms Caldwell was murdered.
The Scottish government last year ordered a judge-led public inquiry into the police handling of the case, which will be chaired by Lord Scott.
In an update on Tuesday, Justice Secretary Angela Constance announced it has now been formally set up and work is under way.
The inquiry will examine the investigative strategy and decision-making by what was then Strathclyde Police, including the direction given by the Crown Office and Procurator Fiscal Service (COPFS).
It will probe what steps could reasonably have been taken that might have resulted in Packer being apprehended and prosecuted at an earlier stage, and any other factors relevant to the circumstances of the investigation and related prosecution.
The inquiry will also examine if any failings in training, procedures, operating models or systems of working contributed to any failures in the police and COPFS case.
The subsequent findings and any recommendations will be reported to Scottish ministers.
Ms Constance said: "My thoughts continue to be with Emma Caldwell's mother Margaret and her family, who have suffered unimaginable heartbreak.
"The public inquiry will look at what went wrong in the investigation of Emma's murder and I hope it will provide the answers that the family need and deserve.
"I consulted with the chair, Lord Scott, on the terms of reference for the inquiry and also met the Caldwell family and other parties to discuss the inquiry's remit.
"While these terms do not feature all of the issues raised with me during discussions, I am satisfied that they are both well focused and sufficiently flexible and broad enough to allow the chair to examine wider issues he may consider relevant to a robust, efficient and effective inquiry."
Ms Caldwell vanished in April 2005 just days after telling her mother about her hopes to defeat a heroin addiction, which began after her sister's death.
She went missing in Glasgow while working as a sex worker. Her body was discovered the following month in Limefield Woods, South Lanarkshire.
Investigating officers interviewed Packer that June but he was not convicted until almost two decades later after cold case detectives re-examined the case in 2015.
Police Scotland apologised to Ms Caldwell's family and Packer's other victims for how the original inquiry was handled by Strathclyde Police, saying they were "let down".
Margaret Caldwell, Ms Caldwell's mother, has never given up on her pursuit of the truth.
Solicitor Aamer Anwar, the family's lawyer, said: "The reference to Strathclyde Police in the terms of reference may be interpreted by some to mean that the inquiry can only deal with the police force up until, but not beyond when it became Police Scotland.
"Strathclyde Police ceased on 1 April 2013 when it merged into a single national service, as Police Scotland.
"If this inquiry is to pursue the truth, then it must look not only at Strathclyde Police, but what happened when Police Scotland took over responsibility."
Mr Anwar said Packer's survivors "deserve their place at the heart of this inquiry".
He added: "A toxic culture of misogyny and corruption meant the police failed so many women and girls who came forward to speak up against Packer.
"Instead of receiving justice and compassion, they were humiliated, dismissed and in some instances arrested, whilst the police gifted freedom to an evil predator to rape and rape again."
