Prime Minister Benjamin Netanyahu will not agree to share the premiership with Zionist Union leader Isaac Herzog in a 'rotation government' following the election, Communications Minister Gilad Erdan (Likud) told a town hall meeting in Tel Aviv on Saturday. The latest polls show Zionist Union with a four-seat lead over Likud, prompting speculation that if the results are borne out in this week's election, Netanyahu will have no choice but to invite Herzog into a unity government in which both men will share power. '[Netanyahu] will not be prime minister in a rotation arrangement,' Erdan said.
