Benjamin Netanyahu is likely to be reelected, albeit with less of a majority than last time.
Analysts say Mr Netanyahu is likely to form a new right-wing coalition.
Unlike previous elections, the Israeli-Palestinian peace process has not been high on most parties’ campaign agendas.
Social and economic issues have emerged as key concerns among voters in the run-up to the polls.
According to final opinion polls, Mr Netanyahu’s joint Likud-Yisrael Beitenu party list will win about 32 seats – down from the previous election but enough to form a majority with right-wing parties.
A right-wing bloc is expected to give Mr Netanyahu support of about 63 seats in the 120-member Knesset (parliament).
