Judges for Kenya's first ever Supreme Court have taken their oath of office in the country's capital, Nairobi.

President Mwai Kibaki and Prime Minister Raila Odinga were among government officials attending Friday's ceremony at the State House.

The Supreme Court judges include Phillip Tunoi, Jackton Ojwang, Mohamed Ibrahim, Charles Wanjala and Njoki Ndung'u.

Their confirmation came a day after a High Court judge threw out a challenge to their appointment.

The Nation newspaper says the judges have made setting a date for the next General Election their first assignment.

The Supreme Court's leaders are Chief Justice Willy Mutunga and Deputy Chief Nancy Baraza.
