Eisenkot, 66, a political novice who has vowed to bridge Israel's deep polarisation under Netanyahu, formally received a mandate from President Isaac Herzog, giving him 28 days to form a government despite his bloc lacking a clear majority.

"We are in a state of emergency, approaching a point of no return for the State of Israel," Eisenkot, who had traded his usual all black for a suit and tie, said at a ceremony at the presidential office.
