The Wiper Democratic Movement (WDM) has once again faulted the Orange Democratic Movement (ODM) over its conduct.
This comes only a week after the two parties faced off in the concluded Embakasi South parliamentary by-elections, a race that was won by the Kalonzo Musyoka-led Wiper side.
But the party on Thursday took issue with ODM's utterances during the campaigns, accusing some of its leaders of insulting the party and its leadership.
Mavoko MP Patrick Makau picked up on ODM Secretary General Edwin Sifuna for allegedly hurling the insults.
He warned that the same could lead to a separation, considering that the two are sisters in the National Super Alliance (NASA).
"It was unfortunate and expensive that a coalition member party took us through all that.
I want to tell ODM that we have seen the insults that you hurled at us and at our party leader, we are not going to do business as usual," the MP was quoted by the Nation.
His remarks were echoed by the Embakasi East MP-elect Julius Mawathe, who vowed to see to it that Wiper cuts links with ODM should Sifuna not be tamed by his party.
"Sifuna is a huge disservice to the party (ODM), if he continues like that I will make sure that we do not walk together," he said.
Mawathe defeated ODM's candidate Irshad Sumra and 14 other candidates in the race to retain the seat which he had won in the 2017 elections, before the court nullified his election.
The leaders were speaking in the presence of Musyoka during his reception of Mawathe at the party headquarters in Nairobi.
