Kizza Besigye, who faces treason charges, is reported to be ‘unconscious’ in hospital after collapsing in court.

Detained Ugandan opposition leader Kizza Besigye has been hospitalised in an unresponsive state after he collapsed during a court hearing on Wednesday, according to his wife.

Besigye, who has been in prison since late 2024 on treason charges, is now “unconscious, unable to speak, and unresponsive”, his wife, Winnie Byanyima, said in a post on X on Thursday.

He has been admitted to the intensive care unit at Mulago National Referral Hospital in the capital, Kampala, added Winnie Byanyima, who also ‌heads the United Nations AIDS programme UNAIDS.

Byanyima has called for her husband to be transferred out of Mulago hospital, a public facility, and into a private facility where he can be treated by his personal physician.

“[Besigye’s] family is saying he needs special treatment and they do not trust the government hospital,” reported Al Jazeera’s Catherine Soi from Nairobi in neighbouring Kenya.

“There’s a lot of frustration. The court has not granted that permission for him to be transferred.”

‘Not responding to anything’

Besigye, 70, was seen falling into the dock during his Wednesday courtroom session while protesting against his trial without lawyers of his own choosing, after authorities also detained and charged his main lawyer, Erias Lukwago.

“Before he collapsed, he cried out that he was being injured,” said Byanyima.

Ingrid Turinawe, a close confidant of Besigye, told The Associated Press that she and others were not allowed to see Besigye at Mulago hospital.

“He is in the ICU, and he is not responding to anything,” she said, adding that Besigye’s personal physician was able to see him several hours after he collapsed.

Besigye, a former ally-turned-critic of longtime President Yoweri ‌Museveni, has been in custody since November 2024. He was jailed together with his aide Obeid Lutale in Kenya and ⁠both were repatriated to Uganda where they were subsequently charged with treason.

Besigye’s lawyers, ⁠supporters and rights activists say ⁠that the charges are politically motivated and that his prolonged detention is part of an ongoing crackdown on opponents by ‌Museveni.

Both Museveni and his son, military chief Muhoozi Kainerugaba, have already weighed in against Besigye.

Kainerugaba, alleging that Besigye plotted to kill his father, has previously described the opposition figure as “a dead man walking”. And Museveni himself has said Besigye must answer for “the very serious offences he is alleged to have been planning”.

In recent days, prosecutors have moved to present evidence they say will prove Besigye and others plotted to overthrow the government

Museveni, 81, was declared winner of the last election in January although the results were rejected by ‌runner-up ‌Bobi Wine, who has since gone into exile in the United States.
