Israel’s PM Benjamin Netanyahu has warned that a proposed unity government aimed at replacing him would be a danger to the country’s security.
He urged fellow right-wingers not to back a deal after ultra-nationalist Naftali Bennett said he would form a coalition with a centrist party.
Mr Netanyahu’s opponents have until Wednesday to form a government.
If they are successful, it would bring to an end the rule of the country’s longest serving prime minister.
Mr Netanyahu, who faces serious corruption charges and could go to jail, fell short of a decisive majority at a general election in March. It was the country’s fourth inconclusive vote in two years – and again he failed to secure coalition allies.
But his opponents might only be able to form a minority government, propped up by support from Arab members of parliament.
“Don’t form a left-wing government – such a government is a danger to Israel’s security and future,” the 71-year-old, who has dominated Israeli politics for a generation, said on Sunday. He did not elaborate.
Mr Netanyahu accused Mr Bennett of “misleading the public” and of carrying out “the fraud of the century” – a reference to the Yamina party leader’s previous public promises not to join forces with Yair Lapid, the centrist opposition leader.
Mr Bennett, 49, earlier announced in a televised address that his party would join talks to form a unity government.
“Mr Netanyahu is no longer trying to form a right-wing government because he knows full well that there isn’t one. He is seeking to take the whole national camp, and the whole country, with him on his personal last stand,” Mr Bennett said.
“I will do everything to form a national unity government with my friend Yair Lapid.”
Before the announcement, Israeli media reported that under the proposed terms of the deal, Mr Bennett would replace Mr Netanyahu as prime minister and later give way to Mr Lapid, 57, in a rotation agreement. The arrangement has not been officially confirmed.
The proposed coalition would bring together factions from the right, the left and the centre of Israeli politics. While the parties have little in common politically, they are united in their desire to see Mr Netanyahu’s time in office come to an end.
Mr Lapid, a former finance minister, was given until 2 June to form a new coalition government after Mr Netanyahu failed to do so. His Yesh Atid party came second to Mr Netanyahu’s right-wing Likud at the last election.
Netanyahu fight on
After an evening of high political drama on Sunday, Israel is much closer to a new coalition that will unseat its long-time prime minister. But Benjamin Netanyahu should not be written off.
He was quick to respond to the latest announcement with his own appeal to right-wing members of Naftali Bennett’s Yamina party – and those of Gideon Saar’s New Hope – not to join the agreement.
He taunted them by asking “Who will take care of settlements?” and suggested the proposed unity government would offer a weak security cabinet that would be unable to stand up to Israel’s rival, Iran.
If he chips away just a couple of members of parliament with these attacks, then the prospective government could tumble.
On Saturday night, Mr Netanyahu’s Likud party made an offer to Mr Bennett and the leader of another potential coalition party to share the premiership in a three-way split.
However, his offer was rejected. But the prime minister repeated the same option on Sunday.
Under Israel’s electoral system of proportional representation, it is difficult for a single party to gain enough seats to form a government outright. Smaller parties are usually needed to make up the numbers needed for a coalition.
Mr Lapid was initially given a 28-day mandate to form a government, but this was interrupted by the recent 11-day conflict in Gaza.
One of his potential coalition partners, the Arab Islamist Raam party, broke off talks because of the violence. There were also clashes in Israeli cities between mixed Arab and Jewish populations.
