Prime Minister Benjamin Netanyahu's right-wing Likud party won a surprise victory in Israel's election on Tuesday, March 17. Earlier exit polls had suggested a dead heat with center-left Zionist Union, BBC News reported.

With most votes counted, Likud is said to be on course to take 29 seats in the 120-seat parliament, the Knesset, with the Zionist Union on 24 seats. If confirmed, this would indicate another coalition government led by Netanyahu.

Netanyahu would need support from other parties to form a coalition.

In a speech to his jubilant supporters in Tel Aviv after Tuesday's polls closed, Netanyahu said he had already spoken to the leaders of other right-of-center parties about forming a new government "without delay".

He described the vote as a "great victory" for Likud, which had trailed the Zionist Union in opinion polls in the run-up to the election.

Netanyahu said the result was achieved "against all odds".

Speaking after the exit polls were published, Zionist Union leader Yitzhak Herzog told his supporters he was confident of forming the next government. "We have achieved an unbelievable achievement today. I will do all that I can in order to create a real socially minded government for Israel."

When final results are known, President Reuven Rivlin will give the task of forming a government to a party leader who he thinks has the strongest chance of assembling a coalition.

Netanyahu could become Israel's longest-serving leader if he secures a fourth term.

No party has ever won an outright majority under Israel's proportional representation voting system.

Almost 72% of those eligible voted in the election, which ended at 22:00 local time (20:00 GMT). The turnout was four points higher than the previous election in 2013.

Netanyahu had vowed not to allow the creation of a Palestinian state if he wins a fourth term, while Zionist Union has expressed support for a two-state solution and promised to repair relations with Palestinians and the international community.
