Kenya's electoral authority has officially ratified the proposed constitution after two thirds of voters approved the charter that will rewrite the political landscape of east Africa's biggest economy.
Ahmed Hassan, chairman of the Interim Independent Electoral Commission, said the official result was based on votes cast in 207 of the country's 210 constituencies.
"Yes" supporters say they hope the referendum will lead to a new era of peaceful democracy and an end to violence.
Media reports say the new constitution addresses corruption and tribalism which have plagued Kenya since it won independence from Britain in 1963.
