JERUSALEM >> Former Prime Minister Benjamin Netanyahu on Thursday appeared set to return to power as head of Israel’s most right-wing government ever after winning this week’s national election, with the current caretaker prime minister conceding defeat.

Final results showed Netanyahu’s Likud Party and its ultranationalist and religious partners capturing a solid majority in Israel’s Knesset, or parliament.

The strong showing promised to end the political gridlock that has paralyzed Israel for the past three and a half years. But the planned agenda of the new government expected to take office — including an overhaul of the country’s legal system and a tough line against the Palestinians — promises to further polarize a deeply divided nation and risks antagonizing Israel’s closest allies abroad.

Israel on Tuesday held its fifth election since 2019 in a race, like the previous four, that was widely seen as a referendum on Netanyahu’s fitness to rule as he faces corruption charges. While the previous races ended in deadlock, Netanyahu managed a disciplined campaign that gave him the edge over a divided and disorganized opposition.

The acting prime minister, Yair Lapid, conceded defeat and called Netanyahu to congratulate him shortly before the final results were released. Lapid said he had instructed his staff to prepare an organized transition of power.

“The state of Israel comes before any political consideration,” Lapid said. “I wish Netanyahu success, for the sake of the people of Israel and the state of Israel.”

According to the unofficial final results, Netanyahu and his ultranationalist and ultra-Orthodox allies captured 64 seats in Israel’s 120-seat Knesset. His opponents in the outgoing coalition, led by Lapid, won 51 seats, with the remainder held by a small unaffiliated Arab faction. Netanyahu still has to conduct negotiations with his partners.

The election focused heavily on the values that are meant to define the state: Jewish or democratic.

In the end, voters favored their Jewish identity.

Netanyahu’s main governing partner is expected to be Religious Zionism, a far-right party whose main candidate, Itamar Ben-Gvir has built a career on confrontations with Palestinians and espouses anti-Arab views that were once largely confined to an extremist fringe.

The party will be the third-largest in parliament.

Ben-Gvir says he wants to end Palestinian autonomy in parts of the occupied West Bank and maintain Israel’s occupation over the Palestinians, now in its 56th year, indefinitely. Until recently, he hung a photo in his home of a Jewish militant who murdered 29 Palestinian worshippers in a 1994 mosque shooting in the West Bank.

Ben-Gvir has labeled Arab lawmakers “terrorists” and called for their deportation.
