The alliance wants the changes— including firing of 11 top officials accused of bungling August 8 poll, dropping of Dubai-based ballots printer Al Ghurair and French technology supplier OT-Morpho— effected before repeat presidential election.
IEBC on Wednesday the election would proceed as planned on October 26 despite Nasa leader Raila Odinga’s withdrawal, a move the commission said was yet to meet statutory and legal requirements.
Mr Odinga bowed out of the race citing refusal of IEBC to implement reforms to guarantee "a free, fair, credible and verifiable election".
At the same time, the CS has said that the government would charge Nasa Chief Executive Norman Magaya for calling the demos that turned chaotic on Wednesday.
Some businesses were looted and property destroyed during the protests in Kisumu and the capital Nairobi.
“We shall prefer charges against him because he is the one that called the demos, after we have quantified the extent of the damage,” Dr Matiangi told journalists at Harambee House in Nairobi.
The CS called on traders who lost their property during the demos to record statements with the police.
He said that the law requires one to notify the police of the demos, its route, its purpose, and await a response allowing it or turning it down, before proceeding for them.
Mr Magaya did comply with the law, the CS said.
