Former Gatanga MP Peter Kenneth lost the primaries to Nairobi Senator Mike Sonko.
Before the nominations Sonko had threatened to ditch Jubilee party if by any chance he lost the nominations.
His close opponent Peter Kenneth running for the same position lost the primaries and has now made his decision.
Mike Sonko had earlier called upon him to join the team and help win the general elections against current governor Evans Kidero but he refused.
Now Kenneth plans to go as an independent candidate and has urged his supporters to come and vote him in as the next governor.
