Voting has opened in the Ol Kalou parliamentary by-election, with 73,480 registered voters across five wards expected to cast ballots at 144 polling stations.
Nine candidates are on the ballot, but the race has narrowed into a high-stakes contest between United Democratic Alliance (UDA) candidate Samuel Muchina Nyagah and Democracy for Citizens Party (DCP) candidate Sammy Kamau Ngotho, a proxy battle between President William Ruto and his former deputy Rigathi Gachagua.
The seat fell vacant after Member of Parliament (MP) David Kiaraho died in March while undergoing treatment at a Nairobi hospital.
