The Kenyan opposition leader said the electoral commission had failed to implement the essential reforms that his coalition had demanded after the Supreme Court threw out President Kenyatta's victory in the first vote held in August, citing irregularities.
Kenya opposition leader, Mr. Odinga had announced his withdrawal from the presidential re-run elections scheduled for October 26.
Kenyatta was displeased with the Supreme Court's ruling calling them crooks.
The dilemma will be whether it is still in public interest to conduct an expensive repeat election or just declare Kenyatta as President of the Republic of Kenya.
The statement further said the commission had taken the necessary steps to guarantee a credible fresh presidential election. "If he has chosen not to run, we are ready for the elections with or without the NASA candidate on the 26th of October this year, and the people of Kenya will decide".
The government is keen to avoid a constitutional crisis if Odinga pulls out at the last minute, frustrating the court's order to hold elections within 60 days, Muturi said.
"The only election Jubilee is interested in is one that it must win, even unlawfully", he said, referring to Kenyatta's party.
His party, the National Super Alliance (NASA), had vowed not to take part in the poll re-run unless the election commission was reformed.
Kenyatta said he was not deterred by Odinga's decision.
Previous tolls from the disputed elections - since annulled by the Supreme Court - had not exceeded 24, and until now there were few details into how the deaths occurred.
During a press conference in Nairobi, he said he could not be sure that the October 26 poll would be free, fair and credible so he dropped out.
NASA's main bone of contention is anchored on the electoral changes that were being debated by Parliament.
Pundits agreed that east Africa's largest economy was staring at a new wave of political stalemate that bodes ill for Kenya's ability to remain stable and hasten economic growth.
In response, the election commission said on Twitter that it was meeting with its legal team and "will communicate way forward".
Opposition lawmakers had also said on Tuesday they would boycott the elections.
According to figures released by IEBC chairman Wafula Chebukati, the incumbent garnered 8,203,290 votes while Odinga managed 6,762,224 votes.
