With 99% of votes counted, Kadima leads Likud 28 to 27 seats
Not certain that Livni will be able to build the 61-seat coalition needed to lead the country.
With 99 percent of the votes counted, Foreign Minister Tzipi Livni's Kadima Party is in first place with 28 of the Knesset's 120 seats, with Benjamin Netanyahu's Likud Party following closely behind with 27 seats.
As the vote progresses, Labor stands at 13 seats, while Avigdor Lieberman's Yisrael Beitenu party is expected to garner 15 seats.
Exit polls by Israel's three main television stations on Tuesday night came to the same conclusion with Kadima as the leader and Likud coming a narrow second.
Channel 1, Channel 2 and Channel 10 polling of voters as they left the ballot box all pointed to victory for Kadima, headed by Tzipi Livni.
If the exit polls are correct, the right-wing bloc, led by Likud leader Benjamin Netanyahu, will comprise 63-64 seats, while the center-left bloc, headed by Livni, will take 56-57 seats. This means that a win in the polls does not necessarily mean that the next government will have a center-left bent.
Televised exit poll results
The Channel 1 poll gave Kadima 30 seats, Likud 28 seats, and Labor 13 seats. Yisrael Beiteinu is predicted to win 14 seats, according to the poll.
