National Super Alliance (NASA) leader Raila Odinga has called for the formation of an interim government to allow for the review of the constitution.
Speaking during an interview with Reuters on Tuesday, Raila said the caretaker government will run the country for a period of six months while the constitution is amended to reduce the authority of the president.
Raila indicated he is ready to engage President Uhuru over constitutional changes that can lower possibilities of violence from minority groups who feel left out of power.
"A pure presidential system enhances ethnicity because each community believes that they are not safe unless their man is at the top," Raila said in the interview in his office.
He added: "We had a new constitution that we enacted in 2010; we think that now it is time to revisit it."
The Orange Democratic Movement (ODM) party leader said the review will focus on strengthening institutions and cut powers held by the President.
"A constitutional review could strengthen institutions like the election board and cut down the powers of the presidency, he said.
"We think that maybe six months will be required to carry out all these changes that we need in this country."
President Uhuru was declared the winner of the controversial October 26th repeat presidential election boycotted by the opposition leader. He will however wait for the Supreme Court to determine petitions filed before it challenging his re-election. If the apex court validates his victory, Uhuru will be sworn into a second term in office seven days after the courts delivers its verdict. The country will go for a fresh election within 60 days should the court nullify his win.
