Kenya opposition presidential candidate Raila Odinga has said the electoral commission’s IT system has been hacked to manipulate the election results, BBC report.
He rejected provisional results from Tuesday’s vote indicating a strong lead for President Uhuru Kenyatta.
Kenya’s election chief Wafula Chebukati said he had confidence in the system but the claims would be investigated.
Many fear a repeat of the violence after a disputed election 10 years ago, and there have been calls for calm.
More than 1,100 Kenyans died and 600,000 were displaced following the 2007 vote.
Raw polling data published on the website of the Independent Electoral and Boundaries Commission (IEBC) says that with 95.3% of results in, Mr Kenyatta is leading with about 54.3%, to Mr Odinga’s 44.8% share of the vote.
These results mean Mr Kenyatta appears to be heading for a first-round victory, but they are not officials results, Mr Chebukati said, as Form 34As – filled in by presiding officers to tally votes at polling stations – have not yet been verified.
This will cause “serious political instability” if unaddressed, the Kenya Human Rights Commission said in a statement.
Mr Odinga has disputed these provisional results, saying in a tweet that his party’s own assessment puts him ahead of Mr Kenyatta.
Local election observers say they are unable to support or dismiss Mr Odinga’s claims, as they are yet to complete their parallel vote tally. The EU observer mission has yet to comment.
