Israeli Prime Minister Binyamin Netanyahu is set to be questioned by police for the fifth time in relation to two ongoing corruption probes. In so-called Case 1000, the premier is suspected of accepting expensive gifts totaling $200,000 from supporters, whereas Case 2000 focuses on an alleged deal—which never materialized—that would have seen Netanyahu receive more favorable coverage in the Yediot Aharonot newspaper in exchange for his support of a bill to weaken the rival Israel Hayom daily. According to reports, the prime minister is expected to be confronted during Thursday’s investigation with testimony from Ari Harrow, his former top aide who turned state’s witness; this, following the questioning earlier in the week of Israeli Ambassador to the U.S. Ron Dermer, a close Netanyahu confidant. The premier’s legal troubles have been further compounded by the suspected involvement of other members of his inner circle in Case 3000, an inquiry into Jerusalem’s purchase of Dolphin-class submarines from German shipbuilder ThyssenKrupp. Netanyahu’s top personal envoy Isaac Molcho and his lawyer and cousin David Shimron have been named as suspects in the affair, in which Israeli officials were allegedly paid bribes to influence a decision to buy the submarines despite opposition from the Defense Ministry. Netanyahu has not been named as a suspect in that particular case and, overall, has denied any wrongdoing.
