IEBC chairman Wafula Chebukati was expected to issue his third press briefing since the start of the tallying process but the presser was called off.
Commissioner Juliana Cherera said this was to allow the commission to verify original Forms 34As that had been uploaded to the public portal.
"So ladies and gentlemen, be patient the next brief will be done tomorrow morning," Cherera said.
Forms 34A are used to capture election results from polling centres at the constituency level.
