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 may only be able to form a minority government, propped up by Arab members of parliament.
