President William Ruto's United Democratic Alliance (UDA) party faces a challenge to its recent by-election victory. Two voters have filed a petition contesting the win of Leo Wa Muthende in the Mbeere North by-elections, citing alleged irregularities and claiming he was not a registered voter.

• Wa Muthende secured 15,802 votes, defeating Newton Kariuki who garnered 15,308 votes.
• The petitioners allege Wa Muthende's name change from Leonard Muriuki Njeru was not updated on the Independent Electoral and Boundaries Commission (IEBC) register, rendering his win unlawful.
• The by-election was triggered by Geoffrey Ruku's appointment as Public Service Cabinet Secretary.

The United Democratic Alliance (UDA) party has announced that it will hold grassroots elections in 20 counties early next year, specifically on Saturday, January 10. This decision follows a joint meeting between the UDA Party's National Executive Committee (NEC) and the National Election Board (NEB), chaired by Deputy Party Leader Kithure Kindiki.

• These elections will take place in counties including Baringo, Bomet, Elgeiyo Marakwet, Kericho, and Nakuru.
• NEB Chairman Anthony Mwaura stated that aspirants can register through the party's portal between December 4 and December 23.
• The announcement comes after the UDA party secured 12 seats in recent by-elections conducted on November 27, 2025.
