IEBC commissioners Paul Kurgat, Margaret Wanjala and Vice chairperson Consolata Nkatha announce their resignations during a press conference in Nairobi, April 16, 2018.
Tumult continues at Kenya's independent electoral commission (IEBC) almost seven months after elections ended.
The resignation comes after Chebukati suspended CEO Ezra Chiloba over irregularities in the procurement process.
The three claim the IEBC under the leadership of Wafula Chebukati is dysfunctional.
Mwachanya blames politicians for the commission's woes.
Margaret Mwachanya and Paul Kurgat said the electoral agency's boardroom had turned into a venue for peddling money, misinformation and grounds for brewing mistrust.
In a statement seen by TUKO.co.ke, Orengo demanded the disbandment of the entire commission since it has failed accountability, efficiency and accuracy tests as stipulated in the constitution.
"For far too long and many times, the commission chair has failed to be the steady and stable hand that steers the ship in hard times and gives direction when needed".
The commissioners a year ago refused to step down amid opposition calls on them to resign, followed by protests to force their resignation, leading to scores of deaths.
During the East African country's general election a year ago the commission was at the centre of controversy and was accused by the opposition of tampering with the vote.
"Given this severe deterioration of confidence in the commission chair, we find our position as commissioners under his leadership no longer tenable", she said.
The Commission Secretariat is also limping after the Employment and Labour Relations Court on Friday declined to stop the three months mandatory leave imposed on Chiloba.
After the resignation of the IEBC officials, the commission's head Chebukati has called for a crisis meeting with the remaining officials.
Upon nullification of August 8 polls, commissioner Roselyn Akombe was first to exit the scene, citing external interference in the commission.
