Israeli Prime Minister Benjamin Netanyahu faces a battle for political survival in a closely fought election on Tuesday that could end his 10-year domination of national politics.

Opinion polls put former armed forces chief Benny Gantz’s centrist Blue and White party neck-and-neck with Netanyahu’s right-wing Likud, and suggest the far-right Yisrael Beiteinu party could emerge as kingmaker in coalition talks.

The two main parties’ campaigns in Israel’s second parliamentary election in five months point to only narrow differences on many important issues: the regional struggle against Iran, ties with the Palestinians and the United States,and the stable economy.

An end to the Netanyahu era would be unlikely to lead to a big change in policy on hotly disputed issues in the peace process with the Palestinians that collapsed five years ago.

Netanyahu has announced his intention to annex the Jordan Valley in the occupied West Bank, where the Palestinians seek statehood. But Blue and White has also said it would strengthen Jewish settlement blocs in the West Bank, with the Jordan Valley as Israel’s “eastern security border”.

The election was called after Netanyahu failed to form a coalition following an April election in which Likud and Blue and White were tied, each taking 35 of the 120 seats in the Knesset, or parliament.

Netanyahu, 69, has cast himself as indispensable and blighted by voter complacency over his tenure – the longest of any Israeli prime minister. He was prime minister from June 1996 until July 1999 and has held the post since March 2009.

Warning he may be replaced by “leftists” who would weaken Israel in the eyes of both foes and friends, Netanyahu has flooded the airwaves and social media with calls on his Likud faithful to turn out in force.

“It’s up to you! The Likud lead is very small,” he appealed hoarsely in a video message posted on Twitter.

Polling stations are open from 7am until 10pm when Israeli media will publish exit polls giving a first indication of the outcome.

Both Netanyahu and Gantz, 60, have tried to energise their bases, and poach votes from smaller parties.

Netanyahu portrays Gantz as inexperienced and incapable of commanding respect from world leaders such as US President Donald Trump. Gantz accuses Netanyahu of trying to deflect attention from his possible indictment on corruption charges that the prime minister has dismissed as baseless.
