The High Court on Thursday nullified the election of Embu Governor Martin Nyaga Wambora.
The court ruled that there were irregularities in the race taht undermined the electoral process.
Last month the same court ordered a fresh tallying and scrutiny of votes in the Embu gubernatorial election in 710 polling stations across the county.
The order came after former Embu Senator Lenny Kivuti filed a petition challenging Governor Wambora’s win in the August election.
On Thursday, Justice William Musyoka said former Senator Lenny Kivuti, who has contested Governor Martin Wambora’s win had demonstrated that there were numerous errors in the tallying exercise.
In the tightly contested gubernatorial race held last year Wambora garnered 97,544 votes against Kivuti’s 96,597.
Thursday’s ruling was eagerly awaited by supporters of both politicians.
Musyoka cited cases where Wambora got more votes in certain polling stations surpassing the number of registered voters.
He furthered ordered Wambora to pay Kivuti a total of Sh2 million in costs.
Wambora is the third Governor to have his victory nullified after Wajir’s Mohamed Abdi’s and Homa Bay county’s Cyprian Awiti.
