Odinga sworn in as Kenyan premier
The BBC article has the detailed story of this phenominal move in Kenya.
Kenya's opposition leader Raila Odinga has officially become prime minister at the swearing-in of a coalition cabinet.
There was applause at State House after Mr Odinga read out his oath of office to be "faithful to the president of the Republic of Kenya".
His cabinet post is a key element of the power-sharing deal with President Mwai Kibaki to end a post-poll crisis.
Some 1,500 people died and 600,000 fled their homes in violence after a disputed presidential poll in December.
