Seven MPs from Kakamega County have vowed to skip Cotu Secretary General Francis Atwoli's planned meeting on Saturday.
Majority of the MPs from the county said they will not attend the meeting scheduled to take place at Bukhungu Stadium.
The main agenda for the convention is to announce the spokesperson for the Luhya community.
Legislators Benjamin Washiali (Mumias East), Emmanuel Wangwe (Navakholo), Andrew Toboso (Butere) and Bernard Shinali (Ikolomani) said they will skip the event.
Others expected not to attend include Malulu Injendi (Malava), David Were (Matungu) and Benjamin Andola of Khwisero.
They said they were not consulted and were not aware of the agenda of the meeting.
The Star reported on Friday that the lawmakers criticised the Cotu boss for sidelining them in identifying the community spokesperson.
"The Luhya nation is bigger than one person. Atwoli should have consulted other leaders from the region before settling on a candidate of his choice. We cannot blindly follow his leader of choice," Washiali was quoted by the Star as saying.
Mr Wangwe on his part said: "What this community requires is a focused, non-partisan person, full of wisdom and who can address issues of the community without political interests. We are afraid Atwoli will impose on us one of his friends from the opposition side."
Atwoli also recently said he would announce a Luhya presidential candidate before January 1.
