Kenya’s defeated presidential contender Raila Odinga has filed a challenge to his election defeat, as police fired teargas to disperse his supporters who had gathered in front of the Supreme Court where the decision will be made. Lawyers for Odinga, who is Kenya’s prime minister, called their petition before the Supreme Court on Saturday a “legitimate legal process” that ensures the will of the people is respected. Odinga refuses to accept the slim first-round win by his opponent Uhuru Kenyatta, alleging collusion between the president-elect and the electoral commission. Al Jazeera’s Nazanine Moshiri, reporting from Nairobi, said that the Supreme Court had two weeks to decide to uphold the decision of Kenyatta as president or to have a run-off. “Odinga regrets that five years ago, when he felt the election was stolen from him, there was no process for him to identify those responsible for election crimes.” Our correspondent said. At least one person was wounded on Saturday as police quickly cleared the crowd from the front of the court building. Some of the supporters wore T-shirts marked with slogans “I support the petition” and “Democracy on trial”, an echo of Odinga’s statement that his petition would be a test of democracy in Kenya.
