Matti Tuchfield writes about such a scenario:
“A Likud government with defectors from the left-wing bloc: If Netanyahu wins 60 seats or less for the right-wing bloc, he will seek to enlist as many MKs as possible from Blue and White and Yisrael Beytenu before surrendering his mandate from the president to form a government.
“During the May 2019 election, Netanyahu made a last-ditch effort to enlist Labor, which was headed at the time by Avi Gabbay, into his coalition. Gabbay, however, decided at the last minute not to join and the Knesset was dispersed. Netanyahu will try it again this time around, in the case of another deadlock. With that, the law makes it hard to resign from a party and such a move entails sanctions on defecting MKs, such as revoking their ability to later run for Knesset on an existing party ticket. This could easily deter MKs from leaving Blue and White or Yisrael Beytenu for the coalition.”
