The upcoming Ol Kalou by-election on June 16, 2026, is shaping up to be a close contest primarily between the United Democratic Alliance (UDA) and the Dignity and Compassion Party (DCP).

• The vacancy arose following the death of the late MP David Kiaraho.
• UDA has nominated Muchina Nyaga, while DCP is fielding former MCA Kamau Ngotho.
• The election is seen as a battle of supremacy between President William Ruto (representing UDA) and his former deputy, Rigathi Gachagua (associated with DCP's growing popularity in the region).
