Tanzania's main opposition party, Chadema, has been disqualified from participating in this year's elections due to its failure to sign a code of conduct document required by the Independent National Elections Commission. This decision arrives just days after Chadema's leader, Tundu Lissu, was arrested and charged with treason for remarks made at a rally where he called for crucial electoral reforms.

Ramadhani Kailima, the commission's director of elections, confirmed that any party not signing the code will be unable to participate in the upcoming elections scheduled for October. He also stated that Chadema would be prohibited from entering any by-elections until 2030. This disqualification is likely to strengthen the ruling party, CCM (Chama Cha Mapinduzi), which has maintained political power since 1977.

Lissu, expected to challenge incumbent President Samia Suluhu Hassan, has rallied for reforms under the slogan "No Reforms, No Election," stressing the need for substantial changes to the electoral commission. This organization's current structure comprises members directly appointed by the sitting president, a situation Lissu argues undermines electoral integrity.

The political landscape in Tanzania has become increasingly tense, with allegations of a crackdown against opposition voices and incidents of arrests and abductions. While authorities assert the charges against Lissu are about public safety, his lawyer claims they are rooted in political motivations. Lissu has a history of clashes with the Tanzanian government, including surviving an assassination attempt and facing multiple arrests.

His treason case has been postponed until April 24, raising concerns about the future of opposition in Tanzania as the country approaches critical parliamentary and presidential elections.
