Benjamin Netanyahu’s chief rival has failed to form a new government, pushing Israel closer to an unprecedented third election in less than a year.
The announcement by Benny Gantz, leader of the centrist Blue and White party, prolongs the political paralysis that has gripped the nation for the past year.
It also provides a new lifeline for Mr Netanyahu, who is desperate to remain in office as he prepares for an expected indictment on corruption charges.
Mr Gantz, a former military chief, became prime minister designate last month after Mr Netanyahu failed to cobble together a coalition government in the wake of inconclusive September elections.
But during four weeks of intense negotiations, Mr Gantz was unable to muster the support of a required majority in the 120-seat parliament.
Under Israeli law, parliament now enters a 21-day period where any MP can try to muster a 61-seat majority and become prime minister.
That means both Mr Gantz and Mr Netanyahu will continue their efforts to reach out to smaller parties, and to explore the possibility of a unity government. Dark-horse candidates may also emerge.
Blue and White said Mr Gantz had informed President Reuven Rivlin that he was unable to form a coalition. He said he would work over the next 21 days “to form a good government for the citizens of Israel”.
Mr Gantz’s Blue and White is the largest party in parliament, with 34 seats, just ahead of Mr Netanyahu’s party Likud, with 33, meaning the two men together could control a majority. But during weeks of talks, they could not agree on the terms of a power-sharing agreement, including who would first be prime minister.
With neither side showing compromise, the country could be forced to hold another election in March. Opinion polls have indicated a new election would deliver similar results to September’s inconclusive vote, signalling additional months of post-election horse trading.
Hovering over the talks, however, is the expected indictment of Mr Netanyahu in a series of corruption cases.
Mr Netanyahu is desperate to remain in the prime minister’s post, which he could use to fight the charges and push for immunity. With the exception of the prime minister, Israeli law requires all politicians to resign if charged with crime.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
