The decisions were reached on Wednesday, August 26, during an emergency meeting of CCM’s Central Committee in Dar es Salaam, a day after Nchimbi announced his resignation from the vice presidency and retirement from politics and public service.

Nchimbi’s resignation is due to take effect on September 4, 2026, and was accepted by President Samia Suluhu Hassan. The appointment of his successor will now follow the constitutional process.

Speaking to journalists after the party meetings, CCM Secretary-General Asha-Rose Migiro said the Central Committee had considered several issues, including disciplinary and ethical matters concerning Nchimbi, who was also a member of the committee.

“After considering all the available information, it was established that the Constitution of Chama Cha Mapinduzi and its regulations had been violated,” Migiro said.

She said the party’s National Executive Committee subsequently resolved unanimously to expel Nchimbi.

“We therefore wish to inform all CCM members and the public that, from this moment, he has been expelled from the party and is no longer a member,” she said.

The expulsion marks a dramatic development in Nchimbi’s political career, which has included senior positions within both the government and CCM.

Nchimbi previously served as CCM secretary-general before becoming Samia’s running mate in the October 2025 General Election. He was sworn in as Vice President on November 3, 2025.

In his resignation statement on Tuesday, Nchimbi said he had decided to leave office after becoming convinced that President Samia wanted a change of vice president.

“I am satisfied beyond doubt that Her Excellency the President wants change, so I have decided to fulfil my promise,” he said.

Nchimbi said his decision was also in line with a commitment he made to Samia in August 2025 to support her and the country with loyalty and step aside if she felt another person was needed as vice president.

Nchimbi's proposed successor currently serves as Minister for Energy and is also CCM’s Member of Parliament for Chamwino. He has previously held several senior government positions.
