A high court in Dar es Salaam, Tanzania's commercial hub, sentenced opposition leader Tundu Lissu to four years in prison on Friday, convicting him of incitement over statements he made before the October 2025 presidential election, according to Genocide Watch. The same court cleared him of treason, the more serious charge he had originally faced, citing insufficient evidence.
Lissu, who leads the main opposition party Chadema, had called on supporters to boycott and disrupt the vote. He told the court the case amounted to political persecution, maintained his innocence and said he would appeal.
Why it matters
The ruling leaves Tanzania's most prominent opposition figure behind bars and, according to his party, could bar him from running in the 2030 presidential election. Genocide Watch reports that human rights organizations view the prosecution as one piece of a wider pattern of repression against dissent.
The case also sits against the backdrop of an election that outside observers criticized. The electoral commission declared incumbent President Samia Suluhu Hassan the winner by a wide margin, but African Union observers said the vote fell short of democratic standards, Genocide Watch reports.
A case that changed shape in court
Lissu was detained months before the October 2025 election and charged with treason. His party, Chadema, was barred from fielding candidates in the contest. On Friday the court dropped the treason count for lack of evidence and instead found him guilty of the lesser incitement charge.
Witnesses described a crowd watching as Lissu was escorted into the courthouse under heavy guard. In his remarks to the court, he insisted he had done nothing wrong and said his party would keep up its fight.
The outcome drew a mixed reaction from his own camp. Some supporters welcomed the treason acquittal but were troubled that he was convicted on a charge that had not been part of the original case. Brenda Rupia, a Chadema spokeswoman, said in an interview that imprisonment should not be counted as a win.
Amnesty International issued a statement calling the proceedings a travesty of justice and urging that the conviction be overturned. A government spokesman could not be reached for comment; the government has said it respects the independence of the judiciary, according to Genocide Watch.
Election violence and a widening crackdown
Election Day protests were met with a security force response in which hundreds of people were killed, Genocide Watch reports — an episode widely seen as a turning point for a country that had long projected an image of stability and social peace.
President Hassan, who took office in 2021 after the death of her predecessor, said she was deeply saddened by the violence and called for reconciliation. She set up a commission headed by a former chief justice to examine what happened. Its full report has not been made public, but the panel placed blame for the unrest on the opposition and outside actors and said police had shown restraint.
The case against Lissu is not his first brush with danger. He survived an assassination attempt in 2017 in which he was shot more than a dozen times. In recent years, other opposition figures and activists in Tanzania have fled abroad, been detained or vanished, according to Genocide Watch.
One of them, human rights activist Twaha Mwaipaya, was seized from his car last week and has not been seen since, according to human rights reports cited by Genocide Watch. Mwaipaya, a former Chadema youth leader who had been living in exile in Kenya, is the latest in a line of disappearances that have alarmed rights monitors.
Political analysts quoted in the reporting describe the Lissu case as evidence of a broader democratic backslide in Tanzania and across East Africa. The country of roughly 70 million people has run multiparty elections since the 1990s, yet it has spent close to five decades under the dominance of a single party, Chama Cha Mapinduzi, known as the Party of the Revolution.
What to watch
Lissu's legal team has signaled an appeal, and how the higher courts handle it — along with any word on Mwaipaya's whereabouts — will be the next test of how far Tanzania's institutions are willing to bend.
