Kenya's main opposition leader Raila Odinga has surprised the nation by withdrawing his candidacy for the fresh presidential election set for later this month. It was his legal challenge that led the Supreme Court to nullify the August election won by President Uhuru Kenyatta and order the new vote. It was the first time a court had overturned a presidential election in Africa. Here's a timeline of the recent developments:

___

Aug. 8: Kenyans vote in presidential election with Kenyatta and Odinga the main challengers.

Aug. 11: Election commission says Kenyatta wins election; Odinga disputes the results as protests break out.

Aug. 16: Opposition announces it will challenge election results in court.

Aug. 19: Opposition files petition with Supreme Court.

Sept. 1: Supreme Court nullifies election, citing irregularities, and orders new vote within 60 days. Kenyatta calls judges "crooks."

Sept. 4: Election commission announces that new vote will be Oct. 17.

Sept. 21: Election commission moves date of election to Oct. 26.

Oct. 10: Odinga withdraws candidacy for the new vote, saying election commission hasn't made requested changes.
