JERUSALEM — The unexpectedly strong showing by a new centrist party in Israel’s parliamentary election has raised hopes of a revival of peace talks with Palestinians that have languished for four years under Prime Minister Benjamin Netanyahu.

Political newcomer Yair Lapid, the surprise kingmaker, is already being courted by a weakened Netanyahu, who needs his support to form a ruling coalition. Lapid has said he will not sit in the government unless the peace process is restarted.

But following a campaign in which the Palestinian issue was largely ignored, it remains unclear how hard Lapid will push the issue in what could be weeks of coalition talks with Netanyahu.

Tuesday’s election ended in a deadlock, with Netanyahu’s hard-line religious bloc of allies and the rival bloc of centrist, secular and Arab parties each with 60 seats, according to near-complete official results. Opinion polls had universally forecast a majority of seats going to the right-wing bloc.

While Netanyahu, as head of the largest single party in parliament, is poised to remain prime minister, it appears impossible for him to cobble together a majority coalition without reaching across the aisle.

Lapid, whose Yesh Atid — or There is a Future — captured 19 seats, putting it in second place, is the most likely candidate to join him. In a gesture to Netanyahu, Lapid said there would not be a “blocking majority,” in which opposition parties prevent the prime minister from forming a government. The comment virtually guarantees that Netanyahu will be prime minister, with Lapid a major partner.

Netanyahu said Wednesday he would work to create a wide coalition stretching across the political divide.

Speaking to reporters, he said the election proved “the Israeli public wants me to continue leading the country” and put together “as broad a coalition as possible.”

He said the next government would pursue three major domestic policy goals: to bring ultra-Orthodox Jewish men, who are routinely granted draft exemptions, into the military, to provide affordable housing and to change the current fragmented multiparty system, which often gives smaller coalition partners outsize strength. 

But Netanyahu only alluded to peacemaking in vague terms, saying coalition talks would focus on “security and diplomatic responsibility.” He took no questions from reporters and immediately walked out of the room.
