Israeli Prime Minister Benjamin Netanyahu and his rival Benny Gantz are struggling over the terms of a unity government after the nation's second election ends in a dead end in one year.
According to local media, both men's parties have not received enough votes Tuesday to build a coalition with the majority.
Mr Netanyahu called on Mr Gantz to open negotiations on joint administration.
Mr. Gantz rejected the idea and called it spin. He said he wanted a unity government ̵
1; but only one of him.
His party has ruled out joining a coalition under the leadership of Mr. Netanyahu, who may be charged with corruption.
