Flamboyant Dagoretti North MP Simba Arati has now turned his guns to Raila Odinga amid controversy surrounding unexpected handshake with Uhuru Kenyatta.
Just a day before ODM's National Executive Committee meeting, Arati, who at one point contested for the party leadership, now wants fundamental changes within the party.
According to the second term MP, the Orange party may not make progress with chairman John Mbadi and Suna east Junet Mohammed continue holding party positions.
"This is something seriously wrong in our party. We cannot succeed if the likes of Mbadi and Junet continue holding party positions.
"Already, they have parliamentary leadership positions and that makes it impossible to deliver at the party level. It is time that Raila Odinga comes out and speaks on this disparity," he said.
While Mbadi serves as National Assembly Minority Leader, Junet is the Minority Whip despite also serving as Director of Elections in the ODM party.
During the March NEC meeting, Arati was due to be elected as Vice Chairman before the decision was rescinded under unclear circumstances by the party.
