A key governing partner of Israeli Prime Minister Benjamin Netanyahu says it is quitting the government, leaving him with a minority in parliament.

Netanyahu’s coalition has been trying to find a path forward on a new law. But his base is largely opposed to granting sweeping draft exemptions and a key lawmaker has stood in the way of giving the ultra-Orthodox a law they can get behind, prompting their exit.

A row over mandatory military service for ultra-Orthodox men has left the prime minister’s ruling coalition with a razor-thin majority.
