counties were also ineligible for a third term. Electoral system The President of Kenya is elected using a modified version of the two-round system: to win in the first round, a candidate must receive over 50% of the vote nationally and 25% of the vote in at least 24 of Kenya's 47 counties. If no candidate achieves this, a second round is held between the top two candidates, in which the candidate with the most votes wins. The Parliament of Kenya consists of two houses: the Senate (upper house) and the National Assembly (lower house), both of which were fully renewed for five-year terms. Those elected in 2022 formed the 13th Parliament of Kenya. The National Assembly has 350 members, of which 290 are elected in single-member constituencies by first-past-the-post voting. Of the remaining 60, 47 are reserved for women and are elected from single-member constituencies based on the 47 counties, also using the first-past-the-post system. The remaining 13 seats include 12 nominated by political parties based on their number of seats and a Speaker, elected by the assembly from outside of it as an ex officio member. The nominated members are reserved for youths, persons with disabilities and workers. The 68 members of the Senate are elected by four methods; 47 are elected in single-member constituencies based on the counties by first-past-the-post voting. Parties are then assigned a share of 16 seats for women, two for youth and two for persons with disabilities based on their seat share. A speaker is also elected as an ex officio member.
