CS Geofrey Ruku has refuted claims of vote buying by the UDA party during the Mbeere North Constituency by-elections held on Thursday, November 27, 2025. These accusations arose after a UDA agent was removed from a polling station for inappropriate attire and alleged bribery.

• CS Ruku defended UDA's conduct, stating there was no voter bribery and that the people of Mbeere North Constituency had already decided Hon. Wamuthembe is their next Member of Parliament.
• The by-elections have been marked by widespread violence, with incidents affecting several prominent figures including aspirant Seth Panyako, Homa Bay Town MP Peter Kaluma, Trans Nzoia Governor George Natembeya, and former Deputy President Rigathi Gachagua, all occurring between November 23 and November 27, 2025.
• The UDA party and the opposition are trading blame, each accusing the other of instigating chaos and attempting to rig the polls.
