Borabu MP Ben Momanyi says Raila Odinga's ODM is undermining Wiper leader Kalonzo Musyoka contrary to the agreement bring the two together.
For weeks now, Kalonzo has been fighting backlash from NASA supporters who accuse him of inconsistency in terms of his political stand.
And Momanyi, whose name was submitted by Wiper for consideration in the PSC, insists that Raila has done little to bring sanity within the orange party.
"His ODM is perpetually undermining Kalonzo and this is setting bad precedence. Our stake within the coalition ought to be respected.
"It is clear that Wipor was prejudiced in nominations to PSC and our party leader was in order to write to the Speaker," he said.
Momanyi, who was among few Wiper leaders to attend Raila's inauguration, insisted that Wiper must get a slot in the PSC.
This comes amidst reports that Raila is keen to invest in his ODM party rather than in the coalition ahead of 2022 polls.
