Borabu Mpesa Ben Momanyi has picked a war with Nasa leader Raila Odinga and is now accusing him of betrayal.
Mr Momanyi said NASA supporters received Raila's decision by a surprise and are not happy about it.
"NASA supporters not only in Nyamira but also across the country are not happy with Raila's decision. NASA supporters have always sacrificed their lives to push for justice in the country but Raila did not take that into consideration before he decided to meet Uhuru to reconcile," said the lawmaker.
He added that Raila should not be trusted because he has proved to be a leader on interested in fame.
"ANC, Wiper and Ford Kenya parties should not trust the old man because he is self-centred. It is time Mudavadi, Wetangula and Kalonzo to pull out from the so-called NASA coalition and form a strong opposition outfit to help opposition clinch presidency in 2022," said Momanyi.
The legislator claimed that ODM party has always sidelined other parties making up NASA when it comes to leadership posts in the National Assembly and the Senate.
"ODM party should be left alone to make up NASA because we have always been left out in the National Assembly and Senate leadership," said the Wiper party MP.
