Israelis vote on Tuesday, Jan 22, in an election widely expected to win Prime Minister Benjamin Netanyahu a third term in office, pushing the Jewish State further to the right, away from peace with Palestinians and towards a showdown with Iran, Reuters reports.

Netanyahu has vowed to pursue the settlement of lands seized during the 1967 Middle East war if he stays in power, a policy that would put him at odds with his international partners and worsen already tense ties with U.S. President Barack Obama.

Polls predict Netanyahu's Likud party, which has forged an electoral pact with the ultra-nationalist Yisrael Beitenu group, will take the most seats in the parliamentary election, albeit considerably fewer than they had originally hoped.

"We want Israel to succeed, we vote Likud-Beitenu ... The bigger it is, the more Israel will succeed," Netanyahu said after casting his ballot alongside his wife and two sons.

Some 5.66 million Israelis are eligible to vote, with polling stations staying open until 10 pm. Full results are due by Wednesday morning, opening the way for coalition talks that could take several weeks to wrap up.

No Israeli party has ever secured an absolute majority, meaning that Netanyahu, who says that dealing with Iran's nuclear ambitions is his top priority, will have to bring various allies onboard to control the 120-seat Knesset.
