Wiper leader Kalonzo Musyoka has convened a meeting with delegates next month to decide whether they will stay in NASA.
The March 16 summit in Nairobi’s will audit the party's position in the coalition and consider options after the disputed 2017 polls.
Officials allege that members of ODM party bully their counterparts and Wiper also believes it got an unfair deal in the alliance after losing a number of leadership slots in Parliament.
In a statement, the party stated: “Kalonzo has been consulting widely on issues which have been fueled by the coalition partners that resulted in name-calling and insults."
Wiper leaders maintained that about 10,000 delegates confirmed they would attend the summit.
The officials further noted that the party would hold two meetings in Kitui and Makueni ahead of the summit to be hosted by Johnson Muthama.
The National Assembly Deputy Minority Leader further maintained that the party was planning a series of activities to activate the grassroots as part of the revamping strategy.
Wiper also noted that the grassroots tour that will follow the summit is meant to solidify the vote-rich base but pundits believe it might also lead to parting ways with NASA.
During the ODM National Delegates Conference on Friday, Kalonzo affirmed that the National Super Alliance was intact.
