Kenya's second Vice President Joseph Murumbi went into history as one of the leaders who held the position for the shortest time, only seven months, before leaving in December 1969.
In his biography "Joseph Murumbi: A Legacy of Integrity" by Karen Rothmyer, which was released in 2018, he comes out as a man who was keenly monitoring fellow politicians.
He says that Kenya's first Finance Minister James Gichuru would have succeeded Mzee Jomo Kenyatta as President, but his love for the bottle swayed him, landing him elsewhere.
He says that Gichuru had the chances of taking Kenyatta's position but “allowed himself to become the victim of drinking".
About Mbiyu Koinange, he says, the Pan African Affairs Cabinet Minister lacked respect for the head of state, hence their severed relationship at the end which didn't allow him to grow further.
He also accuses former Labour Minister Tom Mboya of working with his (Mboya) allies to finish him (Murumbi) politically.
"…I used to feel pinpricks now and again, and I saw the hand of Mboya,” reads the book in part.
Murumbi claims that the then Nyandarua North MP Josiah 'JM' Mwangi Kariuki had mouth to blame for his 1975 assassination, at a time when JM was publicly criticizing Kenyatta.
The book also reveals that Murumbi's term was actually even shorter, as he resigned a few months before he officially vacated the office he inherited from founding Vice President Jaramogi Oginga.
Murumbi who also served as the Cabinet Minister for Foreign Affairs between 1964 and 1966 died on June 22 1990.
