Former general Benny Gantz faces a reckoning next week over his revolt against Israeli Prime Minister Benjamin Netanyahu, who has been gaining ground in opinion polls almost nine months into the war in Gaza.

On Thursday, Gantz's centrist party proposed a bill to dissolve parliament, days after he said he would quit Netanyahu's wartime unity government unless the prime minister came up with a clear day-after strategy for Gaza.

But with the latest opinion poll showing a noticeable swing toward Netanyahu, who received wide support in Israel after International Criminal Court prosecutors said they had requested an arrest warrant against the prime minister, the way ahead has become more complicated.
