Veteran Ugandan opposition figure Dr. Kizza Besigye will remain in custody after the High Court on Friday denied him bail, nearly five months after his arrest.

The 68-year-old medical doctor turned politician and his aide, Hajj Obeid Lutale, have been held on remand for 147 days since their arrest in Nairobi, Kenya, in November last year.

The court acknowledged that both men had presented valid sureties and met formal bail conditions. However, Justice Rosette Comfort Kania, whose ruling was delivered by registrar Ssalamu Ngoobi, ruled against their release, citing the serious nature of the treason charges they face and concerns over potential interference in ongoing investigations.

In her ruling, Justice Kania noted that the allegations span several jurisdictions, both within and outside Uganda, which complicates the investigative process.

“The offences are alleged to have been committed not only in Uganda but also abroad, demanding extensive time and resources,” the court stated.

Highlighting the risk of obstruction, the ruling added that releasing the suspects at this stage could jeopardize the integrity of the investigation.

“Due to the gravity of the accusations and the ongoing inquiries, there is a real risk that the applicants might interfere with the process if released at this time,” the court stated.

Dr. Besigye, a four-time presidential contender, and Hajj Lutale are charged with treason—an offence that carries the possibility of a death sentence.

According to state prosecutors, the alleged conspiracy to overthrow the Ugandan government by force was planned between 2023 and November 2024, spanning multiple international locations including Geneva, Athens, Nairobi, and Kampala.

Two other individuals, including Capt Denis Oola and unnamed co-conspirators still at large, have also been linked to the case.
