Prime minister had potentially up to six weeks to form coalition but negotiations with the opposition stalled just days in

Benjamin Netanyahu could inform Israel’s president that he is unable to form a government as early as this week after unity talks with rival politicians broke down at the weekend, his Likud party said.

Israel has entered a period of political paralysis after an inconclusive election on 17 September. Neither Likud nor the opposition Blue and White party, led by ex-military general Benny Gantz, won a clear lead.

Reuven Rivlin frustrated after talks between ruling party and opposition stall

Israel’s president has tasked Benjamin Netanyahu with forming a coalition government, throwing a lifeline to the incumbent prime minister after an inconclusive election threatened to end his political career.

Reuven Rivlin’s offer does not guarantee Netanyahu will lead Israel’s next administration. Before that can happen, Netanyahu has up to six weeks to forge a majority coalition in Israel’s parliament.

Joint List alliance endorse ex-military chief although say they don’t support his policies

Israeli Arab political parties have broken with longstanding precedent and endorsed the ex-military chief Benny Gantz for prime minister, in a bid to prevent the incumbent, Benjamin Netanyahu, from forming the next government.

The dramatic move came after the mainly Arab Joint List alliance won 13 seats in Tuesday’s polls, making the bloc the third-largest force in the 120-seat parliament.

Blue and White leader rejects offer to serve under Likud after close-run Israeli election

Benjamin Netanyahu is furiously manoeuvring to cling to office after his rival Benny Gantz refused to serve under him in a government of national unity following an inconclusive election.

Gantz’s Blue and White alliance is two seats ahead of the Israeli prime minister’s Likud party, according to results published by Israeli media with 97% of the vote counted.

Prime minister cancels trip to UN general assembly to deal with political crisis

Benjamin Netanyahu and the opposition leader, Benny Gantz, have begun what could be a prolonged period of high-stakes political bartering after an inconclusive election in Israel showed neither had a clear path to form a coalition.

Many Israelis hoped the poll, the second in five months, would provide clarity and pull the nation out of a political crisis. But the muddy results that trickled in on Wednesday appeared to deadlock the country instead.

Five possible scenarios for rivals Benny Gantz and Benjamin Netanyahu

Israelis have voted in a second election that has left the country in a political stalemate.

In the coming days, the president will consult party leaders before choosing the person he believes has the best chance of putting together a coalition.

Benjamin Netanyahu’s warnings that Arab parties would topple him may have backfired

It’s become a tired trope of Benjamin Netanyahu’s election campaigns: as the country draws closer to election day the leader ramps up his racist scaremongering suggesting Israel’s Arab minority are preparing to vote en masse.

Infamously in 2015 he said Arabs were “voting in droves”. This year the prime minister almost lost his voice on Tuesday as he shouted through a megaphone to his base. His political rivals in the Arab parties, he screamed, would gather enough parliamentary seats to topple him. “So go and vote!”

Election day is always a national holiday in Israel and today it bright and sunny. Lots of people out on the beach in Tel Aviv and the streets were packed.

Just after midnight here and Blue and White are holding their election party in large hanger on the waterfront that appears to be a music venue. They are even playing trance music. But still pretty empty here, and reports suggest it’s the same at Likud. The exit polls have clearly concerned both parties.

Here’s a little more detail on the comments from the Israeli president, who has indicated a willingness to press party leaders to quickly form a new government.

Rivlin’s office said his nomination of a candidate would be guided in part by the need to avoid a third election after two votes in five months. It said he would meet with party leaders “after he receives a clear picture of the results, and as soon as possible”.
