The Independent Electoral and Boundaries Commission (IEBC) has gazetted Thursday, February 26, 2026, as the date for by-elections in Isiolo South Constituency and three wards in Embu and Kakamega counties, following vacancies that arose over the past year.
Voters in Isiolo South Constituency will elect a new Member of the National Assembly after the seat fell vacant following the death of MP Mohamed Tubi Bidu.
Tubi died on November 12, 2025, while receiving treatment at a hospital in Nairobi.
He was a first-term MP, having been elected in the August 2022 General Election on a Jubilee Party ticket, and served on the Departmental Committee on Environment, Forestry, and Mining. Before entering Parliament, he was the first Speaker of the Isiolo County Assembly from 2013 to 2017.
The by-election will be overseen by Returning Officer Ali Wario Ibrahim, assisted by Deputy Returning Officer Makandi Ann.

In Embu County, by-elections will be held in Muminji and Evurore wards in Mbeere North Constituency.
The seats fell vacant after the sitting Members of the County Assembly- Newton Kariuki (Muminji) and Duncan Mbui (Evurore), resigned to contest the recently concluded Mbeere North parliamentary by-election.
Kariuki was elected on a Devolution Empowerment Party (DEP) ticket, while Mbui was elected as an independent in 2022. In the parliamentary by-election, Kariuki ran on a Democratic Party (DP) ticket, while Mbui vied on Moses Kuria's Chama Cha Kazi (CCK) party. Both lost to United Democratic Alliance (UDA) candidate Leonard Wa Muthende.
IEBC has appointed Njeru Curtis Mawira as the Returning Officer, with Gitonga Charity Kinya serving as Deputy Returning Officer.
