Most of the exit polls have predicted a defeat for the incumbent Congress.
However, outgoing Chief Minister Virbhadra Singh has discounted all the exit polls terming them unscientific. He has even sought a ban on exit polls.
Elections to the state Assembly, which consists of 68 seats, were held on November 9 this year.
The BJP had projected former chief minister Prem Kumar Dhumal as its chief ministerial candidate.
