Mwingi West MP Charles Nguna now wants President Uhuru Kenyatta to work with all leaders as he strives to unite the country.
Nguna argues that Uhuru will not achieve his mission if he ignores other leaders.
Addressing the press at Parliament Buildings in Nairobi on Wednesday, the Wiper MP accused President Uhuru Kenyatta of only consulting NASA leader Raila Odinga in his push to unite the country.
Nguna said the unity talks must be inclusive stating that other opposition leaders among them Kalonzo Musyoka must be fully engaged.
"President Uhuru Kenyatta must stop treating the unity and reconciliation push as an affair between him and Raila Odinga," Nguna said.
The vocal Wiper MP said the country is sharply divided hence need to seek input of all leaders.
He asked President Kenyatta and Raila to expedite the reconciliation process.
Nguna said the delay is causing suspicions among Kenyans.
On Wednesday, during the joint parliamentary address, President Kenyatta said his push to unite the county is on course.
Uhuru promised to work with all leaders in reconciling the country after last year's divisive general election.
