In the first investigation, Netanyahu is suspected of accepting expensive gifts from wealthy supporters, in the form of cigars, champagne and jewelry in return for advancing their interests.
The list of benefactors includes the Hollywood producer and international movie mogul Arnon Milchan who media claim might have benefitted from
Netanyahu’s assistance in obtaining a US visa, advancing a free-trade zone adjacent to the Jordanian border or by receiving shares of a local television news channel.

Meanwhile, a recent poll showed that a majority of Israelis want Netanyahu to resign when his current term ends and only 38 percent believe he should stay in power for another term.
