The running mate of Kenyan presidential candidate Raila Odinga says the vote-counting process from Monday's election "lacks integrity" and should be stopped.
Kalonzo Musyoka spoke to reporters Thursday in Nairobi, while election officials continued to manually count ballots after a new electronic system broke down.
Close to half of the estimated votes were tallied by early Thursday, showing Uhuru Kenyatta leading Prime Minister Odinda by a 53 percent to 42 percent margin.
Officials say the final results could be released as early as Friday, but they legally have until Monday to finish the count.
Despite some problems, international observers have described the vote as transparent and credible.
