Incident

How Tanzania's 2025 election and its aftermath unfolded

Tanzania held its general election on 29 October 2025 with opposition leader Tundu Lissu in detention on a treason charge and CHADEMA barred from the vote by the electoral commission. The commission declared President Samia Suluhu Hassan the winner with 97.66 percent, while protests, a curfew and an internet shutdown followed, and death tolls given by the government inquiry, the opposition and the UN differ widely. Lissu's treason trial reached its final stage in 2026, with judgment due on 6 November 2026.
