From Tanzania and Uganda to Zambia, South Sudan and Lesotho, some of Africa’s biggest political figures are up against the gravest of charges. Are states confronting real threats or reaching for treason laws against their opponents?
Across the continent, treason is pulling opposition politics, disputed elections and struggles for power into the courtroom. The allegations are serious and varied: plotting coups, organizing armed insurrections, acquiring weapons, financing paramilitary operations and, in some cases, actions and statements made during political and electoral campaigns.
And it is not only opposition leaders in the dock. Ministers, MPs, military commanders, businessmen and even a bishop are among those accused.
At the heart of many of these cases is a fierce dispute over what constitutes treason. Governments say they are prosecuting genuine threats to the state. Opposition figures and rights groups say some authorities are turning the gravest of charges into a weapon against political opponents.
The Africa Report looks at who is facing treason charges across Africa, what they are accused of and where their cases stand, as well as others facing related state-security prosecutions.
Brian Mundubile went from presidential challenger to treason suspect in a matter of weeks. Official results from Zambia’s 13 August election gave President Hakainde Hichilema 60% of the vote, with Mundubile taking 38%. Mundubile disputed the result, alleging irregularities.
Police sealed off the courts on the final day for filing election petitions, preventing the opposition from mounting a legal challenge regarding the result before the deadline.
The political confrontation quickly became a criminal case. The day after the election, security forces stormed a property in Lusaka associated with Mundubile and arrested 11 people. Former cabinet minister Mutotwe Kafwaya was killed during the operation.
Authorities say the raid uncovered evidence of an armed plan against the government and allege that people linked to Mundubile were involved. His camp rejects the accusations. Mundubile later took refuge at UN premises in Lusaka before handing himself over to police. He was formally charged with treason on 29 August.
Lawyer and former Minister Makebi Zulu was Mundubile’s running mate in the presidential election and is now his co-defendant. Zulu served as Eastern Province Minister under former President Edgar Lungu and later became a prominent opposition figure.
After the post-election security operation, Zulu and Mundubile sought refuge at the UN premises in Lusaka before surrendering to police. He was subsequently charged with treason and transferred to Mukobeko Maximum Security Prison.
Eighteen people were charged with treason in total, including politicians, businessmen, a cleric and former servicemen. Among the most prominent is George Kangwa Chisanga, the Lukashya MP, lawyer and former president of the Law Association of Zambia. He was among the 11 people detained during the 14 August security operation and is now among the 18 defendants formally charged with treason.
Bishop Trevor Mwamba brings a very different profile to the case. The Anglican cleric and former bishop of Botswana has also been active in Zambian opposition politics. He was detained during the same operation and has since been charged with treason.
Businessman Valden Findlay is another high-profile defendant. A well-known figure in Zambia’s business and political circles, Findlay has had close links to former president Edgar Lungu. He has been charged with treason in the same case and was later transferred to Mukobeko Maximum Security Prison alongside Mundubile and Zulu.
The case also reaches into Lungu’s family. Businessman Patrick Mwansa, husband of Lungu’s daughter Tasila Lungu, was among those detained in the 14 August operation. He too is among the 18 people formally charged with treason. Other defendants include former servicemen and less prominent figures allegedly connected to the purported plot.
The treason cases come amid wider concern over Zambia’s political climate. Gina Romero, the UN Special Rapporteur on the rights to freedom of peaceful assembly and of association, has expressed “grave concern” over what she described as the country’s deteriorating democratic and human rights environment. She called on the government to protect civic space and “immediately cease the criminalization of political dissent”.
Tundu Lissu has spent years confronting the Tanzanian state. The main opposition CHADEMA chairman survived an assassination attempt in 2017, spent years in exile and returned to become one of the sitting President, Samia Suluhu Hassan’s most outspoken opponents.
Ahead of the 2025 election, he led CHADEM’s “No Reforms, No Election” campaign, insisting that Tanzania’s electoral system had to be overhauled before the country went to the polls.
Lissu was arrested after addressing a political meeting in April 2025 and charged with treason. Prosecutors allege statements he made as part of the campaign were intended to prevent the election from taking place.
On 21 August, the High Court ruled that the prosecution had established a case for Lissu to answer, pushing the trial into the defence stage. Lissu denies the charge and says the case is politically motivated.
Few African opposition figures have endured as bruising and prolonged a confrontation with the state as Kizza Besigye of Uganda. The four-time presidential candidate has spent more than two decades challenging President Yoweri Museveni, repeatedly facing arrest, detention and prosecution.
His latest battle is a treason case. Besigye was detained in Nairobi in November 2024 and forcibly returned to Uganda, initially appearing before a military court. The case later moved to a civilian court after the Supreme Court restricted military trials of civilians. Prosecutors accuse Besigye and his co- defendants of plotting to overthrow the government, including allegedly seeking funds and weapons and organizing paramilitary operations. He denies the charges.
His deteriorating health has complicated the trial. Besigye collapsed in court on 29 July and was hospitalised. His wife, Winnie Byanyima, said he has struggled to walk, speak and write, while prison authorities said he has received medical care and remains stable.
Former Kampala lord mayor and People’s Front for Freedom president Erias Lukwago faces imprisonment for treason, essentially, knowing about an alleged treasonous plot by Besigye – and failing to report it.
Few treason defendants carry the political weight of Riek Machar, the former rebel leader whose power-sharing deal with President Salva Kiir helped end South Sudan’s civil war and made him first vice president.
Prosecutors accuse Machar and seven co-defendants of involvement in an attack on a South Sudan People’s Defence Forces garrison by fighters linked to the White Army, a loose band of armed youths.
The other charges against Machar are murder, conspiracy, terrorism and crimes against humanity. He denies responsibility and remains under house arrest.
More than a decade after Lesotho’s 2014 political crisis, former deputy Prime Minister Mothetjoa Metsing is still on trial for treason.
The Lesotho Congress for Democracy leader is accused in connection with the 29-30 August 2014 attacks on police installations that prosecutors say formed part of an attempted coup. His defence disputes that account, arguing that the military operation was intended to disarm the police.
Metsing has pleaded not guilty, and his long-running trial is due to resume on 21 September. Agriculture Minister Selibe Mochoboroane, leader of the Movement for Economic Change, is also on trial in the same case, which also involves former army commander Lieutenant-General Tlali Kamoli, who headed the Lesotho Defence Force during the crisis. He faces treason, murder and attempted murder charges and has also pleaded not guilty.
A separate and highly unusual treason case involves Tšepo Lipholo, an MP and leader of the Basotho Covenant Movement who campaigns for South Africa to return territory he argues was historically part of Basutoland.
Lipholo is accused of involvement in recruiting Basotho men for military training in South Africa as part of an alleged plan to “forcefully reclaim” the disputed territory, but South African police and intelligence authorities said they found no evidence of the alleged military training camps.
In 2025, former Congolese President Joseph Kabila was tried and sentenced to death in absentia by a military court in Kinshasa for treason, war crimes, conspiracy and his alleged links to the Rwanda-backed M23 rebellion.
Kabila denies the allegations and calls the case politically motivated. His party says the prosecution is an attempt to eliminate a major political opponent.
Timipre Sylva, a former governor of Nigeria’s southern Bayelsa state and ex- petroleum Minister, has been drawn into a federal case over an alleged plot to overthrow President Bola Tinubu.
He is facing trial in absentia for allegedly helping to conceal the alleged coup plot. Six other defendants include retired Maj.-Gen. Mohammed Ibrahim Gana, retired naval captain Erasmus Ochegobia Victor and serving police inspector Ahmed Ibrahim, who face 13-count charges including attempted treason and terrorism-related offences.
On 31 August, while still at large, Sylva resigned from the ruling All Progressives Congress (APC), saying the party had departed from its founding ideals.
More than three years after soldiers overthrew President Mohamed Bazoum, Niger’s military rulers have yet to bring the high treason case they threatened against him. He has remained in detention since the July 2023 coup.
Jeffrey Smith, executive director of Vanguard Africa and a campaigner for Bazoum’s release, says the ousted president is effectively being held as a “hostage” and “stripped of immunity” by Niger’s military rulers.
Elsewhere, terrorism, conspiracy and alleged coup plots have also put government opponents in the dock.
Rwanda’s opposition heavyweight Victoire Ingabire, a longtime critic of President Paul Kagame, has been in custody since June 2025 and is being prosecuted alongside eight others.
She is also accused of spreading information prosecutors say was intended to damage Rwanda’s reputation abroad. Ingabire denies the allegations and the trial continues. She was arrested in 2010 after returning from exile to enter politics and was subsequently convicted and imprisoned, before receiving a presidential pardon in 2018. A year before her release, the African Court on Human and Peoples’ Rights ruled that Rwanda had violated her rights to freedom of expression and a fair trial.
Elsewhere, Venâncio Mondlane, who mounted the strongest challenge to FRELIMO in Mozambique’s disputed 2024 presidential election, faces five charges, including incitement to collective disobedience, instigation of terrorism and incitement to terrorism.
His immunity has been lifted, clearing the way for Supreme Court proceedings and potentially putting his 2029 presidential ambitions at risk.
Former Prime Minister Domingos Simões Pereira, who leads the opposition PAIGC, which led Guinea-Bissau’s independence struggle against Portuguese colonial rule, is now a suspect in an alleged October 2025 attempt to overthrow the government. He and his supporters deny the allegations, describing the case as politically motivated.Former President of the Military High Court, Gen. Daba Na Walna, is also implicated in the same case. He and other defendants were placed in pre-trial detention, amid a legal battle over whether military courts have jurisdiction to try the case.
