Former Bomet governor has branded the absence of veteran opposition and Orange Democratic Movement (ODM) leader from Parliament as a mistake.
Isaac Ruto said Sunday in Nakuru that Raila as the leader of the opposition ought to be in Parliament so as to play his role of keeping the government in check from the house.
"We made another mistake, Raila Odinga as the leader of the opposition in Kenya should be in Parliament, " the Chama Cha Mashinani supremo said.
He contended that Raila could not steer the opposition well from outside parliament.
Wiper Party leader Kalonzo Musyoka and Amani National Congress leader Musalia Mudavadi also need to be in the National Assembly, he said.
The three-party leaders have been rallying their elected members of parliament from outside the legislative body.
This is because the constitution, promulgated in August 2010, does not allow one to run for two seats unlike in the previous dispensation where a presidential candidate could run as an MP and president at the same time.
Isaac Ruto appeared to rally behind suggestions to alter the country's governance structure going forward.
He said that he had made his suggestions to the Building Bridges Initiaive (BBI) committee that has been collecting views from Kenyans.
