The Kenyan opposition leader will challenge results of last week's general elections in the Supreme Court, he said Wednesday.
Raila Odinga said that President Uhuru Kenyatta's supporters had hacked servers of Kenya's electoral body and manipulated the figures in his favor.
Speaking at a press conference in capital Nairobi, Odinga said his party had decided to "lay before the world the making of a computer-generated leadership".
"We are seeking to give a chance to be heard to those who braved long lines in the morning chill and hot afternoon on Aug. 8. Mothers with children tied to their back, the sick, people with disabilities, the old and the young."
Odinga condemned the government for raiding offices of rights groups which had expressed concern over how the country conducted the elections.
He added that he will provide evidence to the court against presiding and returning officers, who he accused of rigging the elections.
Kenyatta, a businessman and the son of Kenya's founding father Jomo Kenyatta garnered 54 percent of the votes. Odinga was able to secure 44 percent votes in the elections.
