A high court in Dar es Salaam sentenced Tanzania's main opposition leader, Tundu Lissu, to four years in prison on Friday, according to Genocide Watch. The court found him guilty of incitement over remarks he made before the October 2025 presidential election, in which he called on supporters to boycott and disrupt the vote. The same court acquitted him of treason, citing a lack of evidence, and convicted him on the lesser charge instead.
Lissu was arrested months before the election and faced the treason count, while his party, Chadema, was barred from taking part in the contest. Witnesses told Genocide Watch that a crowd looked on as he was escorted into the courthouse under heavy security.
Why it matters
The ruling keeps the country's most prominent opposition figure behind bars and could bar him from the ballot in 2030, according to a Chadema spokeswoman quoted in the reporting. It also lands against the backdrop of an election that outside observers have criticized. The electoral commission declared incumbent President Samia Suluhu Hassan the decisive winner, but African Union observers said the vote fell short of democratic standards, Genocide Watch reports.
Election Day protests were broken up by security forces in a crackdown that left hundreds dead — an event the outlet describes as a turning point for a nation that had long projected an image of social peace.
Lissu rejects the verdict
Speaking in court, Lissu described the case as political persecution, maintained his innocence and said he would appeal. He added that Chadema would keep up its campaign, according to the reporting.
The government has said it respects the independence of the judiciary. A government spokesman could not be reached for comment, Genocide Watch reports.
Reaction among Lissu's backers was mixed. Some said they took heart from the treason acquittal but were dismayed that incitement — a charge they noted was not part of the original case — produced a prison term.
"It's not a victory to put someone in prison," Chadema spokeswoman Brenda Rupia said in an interview cited by the outlet.
Amnesty International called the proceedings a travesty of justice and urged that the conviction be overturned, according to the reporting.
A wider pattern, analysts say
Political analysts quoted by Genocide Watch read the Lissu case as one sign of a broader democratic rollback in Tanzania and across East Africa. The country of roughly 70 million people has run multiparty elections since the 1990s, yet the Party of the Revolution, Chama Cha Mapinduzi, has governed for close to fifty years.
Lissu himself survived an assassination attempt in 2017, when he was shot more than a dozen times. In recent years, other opposition figures and activists have left the country, been held in custody or vanished, the outlet reports.
The most recent case involves Twaha Mwaipaya, a Tanzanian human rights activist and former Chadema youth leader who had been living in exile in Kenya. According to human rights reports cited by Genocide Watch, he was taken from his car last week and has not been seen since.
President Hassan, who took office in 2021 after her predecessor died, said the election violence left her deeply grieved. She appealed for reconciliation and set up a commission under a former chief justice to examine what happened. The panel's findings have not been released in full, but it placed blame for the unrest on the opposition and outside actors and said police had shown restraint, according to the reporting.
What to watch next is whether Lissu's appeal moves forward and whether the four-year term is used to keep him off the 2030 presidential ballot.
