The leader of Kenya's opposition, Raila Odinga, has claimed that the country's electoral commission's IT system has been hacked to manipulate voting results.
Odinga rejected the results which showed incumbent Uhuru Kenyatta taking a strong lead in the polls. With 91 per cent of the votes counted thus far, Kenyatta has a lead of 54.5 per cent to Odinga's 44.6 per cent, heading for a first-round victory.
To avoid a run-off, a candidate requires 50 per cent plus one of the votes cast and a minimum of 25 per cent of the vote in 24 of the country's 47 counties. Eight candidates ran in this election, none polled more than 0.3 per cent of the vote aside from Kenyatta and Odinga.
Odinga has claimed that hackers accessed the Independent Electoral and Boundaries Commission (IEBC) computer system using the identity of the commission's murdered IT manager, Chris Msando. Msando's body was discovered a few days after he was reported missing last month.
The leader of the National Super Alliance (Nasa) claims that the hackers manipulated the voting system by loading an algorithm which allowed them to alter results and ignore figures transmitted from tallying centres around the country.
He also told journalists that the results were fake as authorities failed to produce documents verifying the results.
The electoral commission did not comment on the allegations, but confirm that a lack of mobile data coverage had delayed the delivery of the supporting documents, which had formed the basis for the opposition's earlier complaint. Apparently one in four voting stations was also without strong mobile phone coverage, forcing officials to drive to the nearest town to send results.
Calls for calm have been issued across the country, as officials try to avoid the violence that erupted after a dispute in elections 10 years ago, which saw more than 1 100 Kenyans killed and 6 000 displaced.
