"The only exit poll that matters is the one that is slated for Friday (the day Lok Sabha results will be out), the rest are all great time pass," he said on Twitter.
He was reacting to the exit polls aired on various TV channels yesterday, which indicated a victory for BJP-led NDA in the 2014 Lok Sabha elections.
Omar questioned the credibility of the opinion polls in view of the vast difference between two surveys in the number of Lok Sabha seats expected to be won by parties in a particular state.
Citing the example of Rajasthan, the Chief Minister wrote: "So one channel gives Congress only two (seats) in Rajasthan & another gives them 14. Did these channels cover the same election"
