In December 2021, Stella Moris, Julian Assange's partner and the mother of his two sons, said the WikiLeaks founder had suffered a small stroke inside HMP Belmarsh, the high-security prison in south-east London where he was being held. According to her, it happened on 27 October 2021, the first day of the High Court hearing in which the United States was appealing against a ruling that had blocked his extradition. She made the claim public on 11 December, one day after the US won that appeal.
The prison service did not confirm the diagnosis, and no medical records were released, so the stroke remains her account rather than an independently verified fact. What is certain is how the story ended: Assange was never extradited. In June 2024 he pleaded guilty to a single charge in a US court on the Pacific island of Saipan, received a sentence equal to the time he had already spent in a British prison, and flew home to Australia a free man.
What Stella Moris said about his health
Moris broke the news on Twitter and then in an interview with the Mail on Sunday. She described what she called a "mini-stroke", saying that afterwards his eyes were out of sync, his right eyelid would not close properly and his memory had become blurry. She told the paper she feared it could be the precursor to a more serious attack.

She tied the episode directly to the legal fight, describing the years of hearings as a constant chess game played over his head. In her words, the endless cases were extremely stressful mentally
. The UK Ministry of Justice declined to comment on an individual prisoner.
A short note on the medicine, since readers often ask: a so-called mini-stroke usually means a transient ischaemic attack (TIA), a brief interruption of blood flow to part of the brain whose symptoms may fade within hours. Doctors treat a TIA as a serious warning sign, because it can be followed by a full stroke. Chronic stress is one of several risk factors researchers study, but nobody outside his medical team could say what caused his symptoms. Anyone who notices sudden facial drooping, weakness or slurred speech in themselves or someone else should call emergency services and talk to a doctor straight away.
Why the timing mattered: the December 2021 appeal
The health claim landed in the middle of a long extradition battle. In January 2021, District Judge Vanessa Baraitser had refused to send Assange to the United States, finding that the risk of suicide in harsh American prison conditions made extradition oppressive. Washington appealed.
On 10 December 2021, the Lord Chief Justice, Lord Burnett, sitting with Lord Justice Holroyde, sided with the US. The judges accepted assurances that Assange would not be held under the most restrictive prison regimes, before or after any trial, unless his own later conduct justified it, and that he could ask to serve any sentence in Australia. That decision sent the case back towards the Home Secretary and further appeals. Moris's announcement the very next day turned attention back to his condition in prison.
What the United States accused him of
The US case grew out of WikiLeaks' 2010 and 2011 publication of material leaked by former Army intelligence analyst Chelsea Manning. According to the Justice Department, this included about 75,000 Afghanistan war reports, around 400,000 Iraq war reports, roughly 800 Guantanamo detainee assessments and more than 100,000 State Department cables.
A first indictment, filed in 2018 in the Eastern District of Virginia, charged him with conspiring with Manning to crack a Pentagon password. Superseding indictments in 2019 and 2020 added counts under the Espionage Act, bringing the total to 18 rather than the 17 often quoted at the time. Supporters frequently cited a theoretical maximum of 175 years. That figure simply added up the statutory maximums of every count; real federal sentences are usually far lower, and none of the charges carried the death penalty.
The prosecution divided opinion sharply. Press-freedom groups argued that charging a publisher under the Espionage Act could threaten journalists who report on classified material. US officials argued the case was about helping a source obtain secrets and publishing documents with the names of informants left unredacted.
Years of confinement before Belmarsh
Concern about Assange's health did not start in 2021. He entered Ecuador's embassy in London in June 2012 to avoid extradition to Sweden, where prosecutors wanted to question him over sexual assault allegations that he denied and that were later dropped. Ecuador granted him asylum, and he stayed in a small set of rooms for almost seven years.
In April 2019, Ecuador withdrew its protection and British police carried him out of the building. He was sentenced to 50 weeks for breaching bail and then held at Belmarsh on remand while the US extradition request went through the courts. Several medical and human rights observers, including the UN special rapporteur on torture at the time, raised alarms about the effects of long isolation on his physical and mental health.
How the case ended in 2024
After the December 2021 ruling, events moved slowly. Moris and Assange married inside Belmarsh on 23 March 2022, and she later took the name Stella Assange. In June 2022, the then Home Secretary, Priti Patel, approved his extradition. In May 2024, the High Court gave him permission for a full appeal on whether he could rely on free-speech protections in a US court.
Before that appeal was heard, the two sides reached a plea agreement. Assange left Belmarsh in June 2024 and, on 26 June, appeared before the US District Court for the Northern Mariana Islands in Saipan. He pleaded guilty to one count of conspiracy to obtain and disclose national defence information and was sentenced to 62 months, matching the time already served in the UK. He landed in Canberra the same evening.
What the episode tells us
The stroke claim is best read for what it was: a partner's report of a serious health scare, made public at a moment when it could influence opinion about a contested extradition. That does not make it untrue, but it does mean readers should separate three things: what Moris said happened, what the courts decided, and what was eventually agreed.
The wider questions remain live. How long should someone be held while extradition appeals run their course? How should courts weigh assurances from a requesting state about prison conditions? And where is the line between publishing leaked secrets and helping to obtain them? The Assange case did not settle those issues in law, because it ended in a deal rather than a final judgment.
