ODM Kibra parliamentary candidate Imran Okoth has officially been declared winner of the hotly contested mini poll.
Speaking after the announcement, Okoth thanked Kibra residents for believing in him, and giving him an opportunity to serve them.
Imran emerged the winner after garnering 24,636 votes against Jubilee candidate McDonald Mariga's 11,230.
He said his first mission as MP would be to reach out to those who never voted for him during the exercise.
"I thank God for my victory. I thank the leaders who stood with me. I was a handshake candidate. I will work with determination and diligence without any fear or favour. My first mission is to unite the residents of Kibra including those who never voted for me. (Namshukuru Mungu kwa ushindi huu…Nawashukuru viongozi wote waliosimama na mimi. Mimi nilikuwa handshake candidate..Nitafanya kazi kwa roho yangu yote, bila ubaguzi na bila ufisadi…Business yangu ya kwanza ni kuwaunganisha wana-Kibra, hata wale ambao hawakunipigia kura)," he said.
The voting exercise witnessed low voter turnout and cases of bribery.
Jubilee candidate Mariga has conceded defeat and assured Imran of his support as he assumes office.
Leaders from different parts of the county have congratulated Imran following the win.
“I know Kibra has made a wise choice. I think Kibra is set. As ODM, we are proud of Imran," Nairobi Woman Rep Esther Passaris said.
"Congratulations Imran Okoth for the emphatic victory in the Kibra parliamentary by-election. This is a clear demonstration of maturity by Kibra electorate, who defied bribery and intimidation. The ODM party has once again sent a clear message to our competitors," Joho wrote.
"Congratulations to Kibra MP elect Imran Okoth and Kibra people for voting in a true son of Kibra. Thank you for honoring the handshake. Walikucheka lakini kwa ground vitu ni different. Long live the Handshake; forward, onward to BBI" Governor Anne Waiguru wrote.
