The husband, Francis Nyenze died in December last year.
Ms Vethi paid Sh200,000 nomination fee to the Kalonzo Musyoka-led Wiper Democratic Movement on Tuesday as well as Sh50,000 life membership fee.
Recently, the IEBC chairman Mr Wafula Chebukati in a statement that at a by-election would be held in Kitui West Constituency on March 26th, 2018. He added that all political parties interested in fronting candidates were to do so by January 10.
“Each Political Party intending to participate in the Kitui West by-election shall submit the names of the persons contesting in a party primary and the date of the party primary on or before 10th January, 2018,” the IEBC had said.
On Wednesday, Kitui Senator Enoch Wambua, who acted as the Nyenze family spokesperson during the funeral arrangements, said Vethi had been cleared to run for office.
Edith will be facing Maluki Kitili, son of former Cabinet minister Nyiva Mwendwa, for the Wiper ticket, setting the stage for an epic battle between the two families.
Nyenze was a close ally of Wiper party leader Kalonzo Musyoka, while Nyiva has always stood with Kalonzo during political storms. The well-heeled Nyiva has been a Wiper benefactor for years.
In a public notice yesterday Wambua indicated that Vethi will formally launch her bid during a rally at Kabati trading centre, a stone’s throw from the Nyenze home.
“Mama Edith Vethi will be launching her bid for the Kitui West parliamentary seat. She is seeking the Wiper ticket for her bid to complete the good work her late husband started,” he said.
She will be accompanied by Nasa leaders from the Lower Eastern region.
The proposal for Vethi to succeed Nyenze was floated during the burial in Kyondoni village, Kauwi ward. Kauwi MCA Jane Mutua said Edith is best placed to take over from her husband.
But Felix Mbevo of Mutonguni ward and Munyallo Kitheka of Matinyanitwo opposed the proposal, saying residents had not been consulted.
Nyenze, 60, died on December 6 after a long battle with colon cancer, which caused his lungs to weaken and he caught pneumonia during the campaigns for the August 8 election.
