Marakwet East MP Kangogo Bowen has lost his seat following a successful election petition.
The High Court in Eldoret on Tuesday found that the August 8, 2017 parliamentary election was marred by irregularities.
Justice George Kimondo established that two ungazetted polling stations were used to tally the final results of the race.
In his decision, Judge Kimondo cited adequate evidence to prove massive irregularities during the election.
The poll, he ruled, was not free and fair as it was marred by multiple irregularities and illegalities.
