The United Democratic Alliance (UDA) party announced it will hold grassroots elections in 20 counties on Saturday, January 10, 2026. This decision was made after a joint meeting of the party's National Executive Committee (NEC) and National Election Board (NEB). Concurrently, President William Ruto's UDA party is facing a legal challenge to a recent by-election victory. Two voters have petitioned against the win of Leo Wa Muthende in Mbeere North, alleging irregularities and claiming he was not a registered voter. In a related development, rights organizations led by Vocal Africa gave the IEBC and EACC a 14-day ultimatum to act on alleged widespread electoral offences during recent by-elections, threatening legal action.
