Throughout their stay in politics, founding Vice President Jaramogi Oginga and cabinet minister Tom Mboya were not in good political terms.
This first came out publicly in the early 60s, when both leaders secured scholarship opportunities in Bulgaria.
Oginga, then the Home Affairs Minister, used his links to secure scholarships for 46 Kenyans but would have the number added to 55 after contacting Bulgaria for the favour.
This was after he heard that Mboya, with whom he was locked in a supremacy tussle, had also been allowed 46 slots, but Oginga was out to make his presence felt.
On the final day, Bulgaria sent in a plane to airlift the beneficiaries to Sofia, and Oginga would wait until Mboya's team was comfortable in the plane, before storming it.
According to Kamau Ngotho, a veteran journalist, Oginga got into the plane, went directly to the pilot and notified him that he had the "wrong cargo" on board.
He then ordered his team to eject Mboya's team, resulting in a clash that saw the police called in to calm the situation at the airport.
As a more powerful minister, he orders were honoured and had Mboya's team ejected from the plane an airport by police.
Though this was a show of division in the cabinet given that Mboya had the approval from the Education Ministry through the then minister Joseph Otiende, Jaramogi had won.
