Israel election: Netanyahu and Gantz compete over leadership
More from the BBC article:
Local media say both men’s parties failed to win enough votes on Tuesday to build a coalition with a majority.
Mr Netanyahu urged Mr Gantz to start immediate negotiations to form a unity government.
Mr Gantz said he wanted a unity government - but only one led by him.
His party has ruled out joining a coalition led by Mr Netanyahu, who faces possible corruption charges.
