If the exit polls turn out to be accurate when the votes are counted on Friday 16 May, they will point to a dramatic turnaround for the BJP and a massive defeat for the Congress.
An election exit poll is a poll of voters taken immediately after they have exited the polling stations. Unlike an opinion poll, which asks whom the voter plans to vote for or some similar formulation, an exit poll asks whom the voter actually voted for. A similar poll conducted before actual voters have voted is called an entrance poll.
The Election Commission said voter turnout was a record 66.38%.
