Azimio La Umoja has declined a meeting convened by Kenya Kwanza and the leadership of Parliament to agree on the resumption of the stalled bipartisan talks.
In a back and forth between the two camps, Raila Odinga's camp said they will not be ready for the meeting planned for May 2.
Incidentally, Azimio has convened street protests on the same day next week despite calls by President William Ruto to call off mass action.
Kenya Kwanza team leader in the talks George Murugara, the chairperson of the National Assembly Justice and Legal Affairs Committee, had called for the session to iron out sticking issues.
However, his Azimio counterpart Otiende Amollo wrote back to Murugara on Friday evening declining the meeting.
"As communicated in our meeting on April 23, our team is not available for any discussion until and unless there is a communication of withdrawal or/and replacement of Adan Keynan as a member of the Kenya Kwanza team," Amollo wrote.
"Given the above, I advise that I shall not be available for the proposed meeting."
Murugara had written to Amollo asking for a meeting between himself, Amollo and the majority and minority leaders of the Senate and the National Assembly next Tuesday.
"I wish to invite you and the House leadership of your coalition to a meeting to be held on May 2, at 1 pm which we will attend as co-chairpersons together with the House leadership," Murugara said on Friday.
The same meeting last week failed to make any progress in agreeing on the composition of the teams representing each side in the talks.
In a separate statement, Murugara said they are willing to withdraw Keynan to salvage the talks but asked Azimio to also recall Pokot South MP David Pkosing'.
Kenya Kwanza said the decision was arrived at to unlock the impasse on the composition of the committee so that the talks can move to the next level.
"To demonstrate our commitment to the one process of a peaceful bipartisan engagement, we are ready to recuse the hon. Keynan the process if the issue they consider to conflict with Keynan will be part of TOR of the formal process," Murugara said.
