More than 1,500 people died in the violence that engulfed the country
Kenya's cabinet has agreed to implement a controversial report into January's post-poll violence, which recommends prosecuting all those responsible.
The meeting to approve the report had been delayed several times.
But a statement from the president's office said there was consensus to carry through the recommendations.
These include an international tribunal to try the politicians and businessmen thought to have organised the violence, in which some 1,500 people died.
Another 300,000 people fled their homes following the disputed elections in Decmber.
President Mwai Kibaki of the Party of National Unity (PNU) and Orange Democratic Movement (ODM) leader Raila Odinga, now prime minister, signed an agreement in February to end the crisis and formed a coalition government.
A commission of inquiry into the violence, chaired by Justice Phillip Waki, published a report last month and handed over a sealed list of suspects to the mediator of the power-sharing deal, former UN chief Kofi Annan.
It was agreed that if an international tribunal was not set up within 60 days, Mr Annan would hand over the names to the International Criminal Court (ICC) in The Hague.
Mr Kibaki and Mr Odinga will now head an eight-man cabinet committee to plan the implementation of the Waki report.
But the BBC's Rob Walker in the capital, Nairobi, says it is still a deeply divisive issue.
Some politicians say the report does not provide enough evidence.
But others say that without a tribunal, those responsible would be free to repeat their crimes.
The cabinet also adopted the recommendations of another commission led by South African judge Johann Kriegler, which called for radical reforms of Kenya's electoral process.
It said the Electoral Commission of Kenya (ECK) should be overhauled or replaced.
However, ECK head Samuel Kivuitu has gone to court to scuttle any attempt to disband the body.
