Former Mombasa Senator Hassan Omar has lodged a petition in the High Court seeking to overturn Mombasa Governor Hassan Joho's victory in the August 8th general election.
Omar filed the petition on Friday, citing massive irregularities during vote counting and tallying of the Mombasa governor seat, which might have favored Joho.
Omar came third in the race for Mombasa governor behind Jubilee's Suleiman Shahbal and ODM's Hassan Joho.
Joho garnered 221,363 votes (64.94%) with Shahbal coming second with 69,429 votes (20.37%). Omar secured 43,790 votes (12.85%)
Omar contested under the Wiper Democratic Movement, a party led by NASA presidential running mate Kalonzo Musyoka.
Omar's decision to petition Joho's win comes barely a day after he tendered a resignation letter as Wiper Secretary General citing personal reasons.
In his resignation letter, he thanked Kalonzo for giving him a chance to serve Wiper.
Omar said he will not actively take part in campaigns for NASA presidential candidate Raila after the Supreme Court overturned the August 8th presidential election.
Anne Waiguru of Kirinyaga and Alfred Mutua of Machakos, Kiraitu Murungi (Meru), Joseph Ole Lenku (Kajiado), Martin Wambora (Embu), Fahim Twaha (Lamu) and Ali Roba (Mandera) are other governors whose victories are being petitioned by rivals.
