Three weeks after Kenyans went to the polls to vote for their president, the country's Supreme Court is about to give its verdict on who won the disputed election.

President Uhuru Kenyatta was announced the winner with 54% of the vote - but his main rival, Raila Odinga, claimed the election was rigged.

Odinga took his case to the country's highest court and on Friday Kenyans will hear the official ruling.
