Kiambaa MP Paul Koinange and his Kiambu Town countepart Jude Njomo have asked President Uhuru Kenyatta to sack suspended Lands CS Charity Ngilu.
The duo have said that Ngilu is no longer loyal to the government and should be left to go and join the opposition.
"The marriage between the government and Charity Ngilu is no more. It is high time she was left to go and find another suitor. Her continued stay in Jubilee is adding us no value but problems," said Koinange.
Njomo asked Ngilu to stop side-shows and concentrate on clearing her name in the corruption case facing her.
"It is disappointing to see Ngilu bringing tribal politics in the corruption case she is facing. This is an individual matter and should remain that way," Njomo said.
The two MPs also condemned Ngilu for defending Wiper Leader Kalonzo Musyoka on the NYS land saga in Yatta.
"Corruption and bad governance are perpetrated by leaders like Ngilu. Why defend Kalonzo when she knows that he did not acquire that land through a proper procedure? She should leave Kalonzo to defend himself," Koinange added.
The two were addressing journalists in Kiambu Town on Wednesday.
