Machakos governor Dr Alfred Mutua joined veteran opposition leader and Orange Democratic Movement (ODM) leader Raila Odinga at the Jaramogi Oginga Odinga Foundation Saturday.
The county supremo was there to express his support for Imran Okoth, ODM's candidate in the Kibra parliamentary race.
He revealed the meeting in a tweet on Saturday.
"At Jaramogi Odinga Foundation offices with @TheODMparty Leader, @RailaOdinga #TeamImran, " his tweet read.'
The meeting comes just days to the Kibra by-election that will be held next week on Thursday 7, November, 2017.
Dr Mutua's support is a shot in the arm to Imran Okoth who is seeking the backing of the KIbra residents to be the next member of parliament of the constituency.
Mutua is in a power struggle with Wiper leader Kalonzo Musyoka for the Kamba nation''s support as both are expected to gun for the presidency in 2022.
Kalonzo Musyoka has avoided the Imran Okoth campaign and the presence of the Machakos governor at an event in support of the ODM candidate is seen as the county boss' challenge to Kalonzo Musyoka.
The Kibra constituency seat was declared vacant after the death of the late former member of parliament Ken Okoth who succumbed to a run with cancer at a Nairobi hospital.
The race has been variously framed as a dress rehearsal for the 2022 presidential race.
Though Dr Alfred Mutua has declared his interest in the top seat, Raila Odinga has remains coy about his 2022 presidential ambitions, choosing to play his cards close to his chest.
