Moses Kuria, a contender for governor of Kiambu, has accepted defeat in the fiercely contested campaign.
The Chama Cha Kazi (CCK) party leader hinted in a brief statement on Tuesday night that his chances of winning the seat were limited.
After serving in parliament for eight years, the departing Gatundu South MP said that he is leaving the field to focus on his private company.
The Independent Electoral and Boundaries Commission has not yet made its official results public (IEBC).
Moses Kuria and Faith Mwaura competed against a number of power players connected to the Kenya Kwanza alliance, which backs Deputy President William Ruto’s presidential campaign.
The candidates are former governor William Kabago (Tujibebe), Mwende Gatabaki (Safina), two-term Kiambu senator Kimani Wamatangi of the United Democratic Alliance (UDA) party, and James Nyoro(Jubilee).
After the passing of the previous MP, the late Jossy Ngugi, Kuria was elected MP for Gatundu South in a by-election without facing any opposition in 2014.
Kuria said in July that Kiambu lawmakers with ties to the United Democratic Alliance (UDA) were conspiring to thwart his run for governor.
Kuria charged that his supposed opponents had halted their campaigning to help Wamatangi, who is also running for the top spot in the County in the August elections.
