Israel’s longest serving prime minister woke up to a throbbing political headache on Wednesday morning after his deadline to form a coalition government expired on Tuesday night. Benjamin Netanyahu, who is fighting for his political survival amid a series of poor election results and a corruption trial, is now looking more vulnerable than ever. The Right-wing Likud party leader had been asked to form a coalition by Israel’s president after the country’s fourth election in two years in March, which failed to produce a clear winner. But after several fruitless weeks of coalition talks and backroom meetings, his deadline for forming a government expired at midnight on Tuesday, plunging his political career into deeper turmoil. It is not the last straw for the embattled leader, who may yet be able to cling on to power if he finds more supporters in the coming days and convinces Reuven Rivlin, the Israeli president, to grant him an extension. But his failure to find a 61-seat majority is delightful news for the so-called anti-Netanyahu bloc of left-wingers and centrists, who now hope to form their own alternative government. Here we look at what is most likely to happen now that Mr Netanyahu’s deadline has expired, and whether there is any hope of ending the worst political deadlock in Israeli history any time soon. Option 1: Netanyahu’s enemies try to form government The next few weeks could get very busy for the anti-Netanyahu coalition led by Yair Lapid, the head of the centrist Yesh Atid party. Israeli media reports say Mr Rivlin is poised to give Mr Lapid the next chance at forming a government within 28 days as his party came second, after Likud, in the March 23 polls. This will not be easy, as the Lapid-led bloc does not currently have a 61-seat majority and would need to unite voices across the political spectrum against Likud, something it failed to do after the previous three elections.
