The parliamentary seat in Ol Kalou
became vacant after MP David Njuguna Kiaraho's death on March 29, 2026, setting
up a contest between UDA's Samuel Muchina Nyagah and DCP's Sammy Douglas Kamau
Waweru on July 16.
Inspector General Douglas Kanja
deployed heavy security, including GSU platoons and water cannons, to curb
reports of goons, bribery, and intimidation.
DCP leader Rigathi Gachagua accused plainclothes officers of voter harassment and called for uniforms and marked vehicles, while government backers hailed it as a crackdown on violence; critics like Pauline Njoroge see it as a sign of potential rigging in this key test of Mt. Kenya politics.
