Ford Kenya party maintains that the NASA coalition is no longer existing even as ODM wing denies shortchanging members.
Even since the surprise unity deal between Raila Odinga and President Uhuru Kenyatta, the opposition coalition has been embedded in a host of wrangles which seems irreconcilable.
And Tongaren MP Eseli Simiyu, who doubles as the party's Secretary General, says the coalition has since collapsed.
"As far as I am concerned and as far as Ford Kenya is concerned, NASA does not exist for any of us," he told NTV's AMLive programme.
He added: "We have suggested that ODM seems uncomfortable with NASA and we have said they should leave. If not, let them forget the whole NASA thing."
Last month, ODM party staged an internal war that saw Ford Kenya leader Moses Wetangula toppled as Senate Minority Leader, a position that was taken by James Orengo.
And even with the current woes within the coalition, Rarieda MP Otiende Amollo says the coalition is still intact.
