The Ol Kalou constituency seat has been formally declared vacant by National Assembly Speaker Moses Wetangula following the death of area MP David Njuguna Kiaraho on March 29, 2026.

• The vacancy was announced in a special Gazette notice on April 20, 2026.
• This declaration will trigger a by-election within 90 days, to be organized by the Independent Electoral and Boundaries Commission (IEBC).
• The upcoming by-election is anticipated to be a contest between the ruling United Democratic Alliance (UDA) and Democracy for Citizens party (DCP), led by ex-deputy president Rigathi Gachagua.

Deputy President Kithure Kindiki has publicly stated he will "embarrass" his predecessor, Deputy President Rigathi Gachagua, in the upcoming Ol Kalou by-election.

• The Ol Kalou by-election was triggered by the death of MCA David Kiaraho in March.
• Deputy President Kithure Kindiki expressed strong confidence in the ruling party winning the seat.
• This statement signals a potential political clash between prominent figures within the government.

The impending Ol Kalou Constituency by-election is prematurely sparking political rivalries, despite a delay by National Assembly Speaker Moses Wetang’ula in officially declaring the seat vacant.

• The vacancy occurred on March 29, 2026, following the death of MP David Kiaraho, but the Speaker has not yet gazetted it by the constitutional deadline of April 19, 2026.
• Four competing political formations have already emerged: UDA, Democracy for the Citizens Party (DCP), Jubilee Party, and allied smaller parties.
• Legal experts view the Speaker's delay as a breach of constitutional mandate, potentially grounds for a court petition.
