Jeremy's Knesset Insider 
So if likud wins by 1 does N get to form a government?
>
The PM is chosen through a 3 phase process.
First phase is Tuesday in the Knesset election.
Second phase is the vote at the President’s Residence by the parties that pass threshold.
Third phase is when the Knesset votes in the new government in a confidence vote (most likely, the first week of June).
