Kitui Governor Charity Ngilu and former Prime Minister Raila Odinga have deep political connections.
The two veteran and experienced politicians have walked together in the past in pursuit of the country's democratic and constitutional reforms.
Ngilu and Raila were part of the team of politicians who ganged up to end retired President Daniel Arap Moi's 24 years rule in the 2002 general election.
The leaders under the National Rainbow Alliance led fierce campaigns in 2002 that saw the now President Uhuru Kenyatta who had been endorsed for the top seat by Moi in 2002 defeated.
Ngilu and Raila alongside other politicians among them the late Kijana Wamalwa and former President Mwai Kibaki crafted the known 2002 Memorandum of Understanding (MoU).
The Raila - Ngilu and other leaders' unity saw Kibaki defeat Uhuru Kenyatta in the historic 2002 general elections.
However, their unity did not last long as the leaders wrangled on how the MoU was to be implemented.
A section of the NARC leaders led by Raila and Ngilu accused Kibaki of disregarding the MoU after winning the election.
Kibaki's allies had allegedly opposed creation of the Prime Minister position that Raila was to take up as part of the MoU.
The wrangles and betrayal of the MoU saw NARC disintegrate in the run up to the 2007 general election.
The party or rather coalition split into two with Ngilu going with the original NARC and former Gichugu MP Martha Karua forming NARC Kenya.
The two factions of the original coalition are still active and Ngilu contested on NARC to win the Kitui gubernatorial seat in last year's polls.
Political analyst Peter Ngure says Ngilu and Raila share rich political history that cannot be disputed.
"The two leaders [Raila and Ngilu] have much in common and their contribution to the country's democratic space is being felt," Ngure told this writer on Friday.
