Tanzania’s CHADEMA Vice Chairman John Heche Threatens Mass Protests Over Tundu Lissu’s One-Year Detention
Ujasusi Blog’s East Africa Monitoring Team | 10 April 2026 | 0115 BST
Tanzania’s main opposition CHADEMA Vice Chairman John Heche has issued a public call for a coordinated, multi-platform campaign demanding the unconditional release of party chairman Tundu Lissu, who has been held in continuous custody since 9 April 2025, exactly one year to the day. Speaking directly to supporters, Heche warned that if the Samia Suluhu Hassan administration refuses to act, CHADEMA will move to a second phase: nationwide mass protests. Whether the party can deliver on that threat is an open question; its own record makes it difficult to avoid.

Lissu’s Detention: The Legal Architecture of a Political Prosecution
Lissu was arrested on the evening of 9 April 2025 following a rally in Mbinga, Ruvuma Region, and transferred overnight — more than 1,000 kilometres — to Dar es Salaam, where he was charged the following day with treason and three counts of publishing false information under the Cyber Crimes Act. The treason charge carries a mandatory death sentence upon conviction.
The prosecution’s case rests on a YouTube address Lissu delivered on 3 April 2025, in which he called for Tanzanians to boycott the forthcoming elections and alleged that the Tanzania Police Force had participated in electoral malpractices under presidential instruction. He has remained in custody without bail since the treason charge rendered him ineligible under Section 148(5) of the Criminal Procedure Code — a provision the African Court on Human Rights has ruled discriminatory and contrary to the presumption of innocence.
The arrest came directly after Lissu was elected CHADEMA’s national chairperson, and he stood as the party’s most credible presidential candidate for the October 2025 general election. Within weeks, the Independent National Electoral Commission barred CHADEMA from contesting the election, and the High Court suspended the party from all political activities. The European Parliament documented the sequencing as a coordinated dual neutralisation of Tanzania’s principal opposition force through judicial and administrative instruments deployed in parallel.
Heche’s Campaign Blueprint: Diaspora Missions, T-Shirts, and a Two-Phase Escalation
Heche directed his appeal at two audiences simultaneously. To Tanzanians inside the country, he called for visible street-level action: T-shirts bearing pro-Lissu messages, flyers distributed in markets, and posters placed on electricity poles and government office buildings. To diaspora communities, he issued a direct instruction: visit Tanzanian diplomatic missions in every country of residence and demand Lissu’s immediate release without conditions.
