Media Council of Kenya has said 34 million Kenyans kept tabs on the deputy presidential debates held on July 19.

Of the 34 million who followed the debate, 18.5 million were registered, voters.
The debate was organized by the MCK, Media Owners Association and the Kenya Editors Guild.

MCK CEO David Omwoyo on Friday said 70 per cent watched the second tier of the presidential debate pitting Azimio presidential running mate Martha Karua and her UDA counterpart Rigathi Gachagua.
5 per cent watched the first-tier debate involving Roots party deputy presidential candidate Justina Wamae and Agano's Ruth Mucheru Mutua. 30 per cent watched both.

A sample of 1,245 respondents with a confidence margin of 95 per cent was polled.
"Three-quarters of the viewers or 76 per cent watched the event on television, 19 per cent followed on the radio while 10 per cent totalling 3.4 Million were on social media," MCK said in a press statement.
"7 million accessed their radios and TV via the internet where YouTube was the main choice clocking 65 per cent followed by Facebook at 31 per cent."
YouTube was the main choice of viewership on the internet at 65 per cent followed by Facebook at 31 per cent.
"While online consumption of media content is increasingly becoming critical, we are cautioning Kenyans to beware of manipulation deliberately pushed by purveyors affiliated to the various political competitors," Omwoyo said.
