Israeli police investigators are questioning Israeli Prime Minister Benjamin Netanyahu's wife, Sarah Netanyahu, on Friday in an investigation into a corruption case, the official Makan radio reported. The prime minister's wife is expected to be questioned by the Israel Police's Lahav 433 anti-corruption unit, where she is suspected of providing misleading information to the State Comptroller about false receipts for donations she was supposed to make instead of paying the salary of her former media adviser, Nir Hifetz. If the evidence is sufficient to indict, it will be added to the well-known case of "habeas corpus" in which Sarah Netanyahu is tried. The State Prosecutor's Office charged her with fraud and dishonesty by spending state money on luxury meals and chef services. Last week, police announced that there was sufficient evidence to accuse Netanyahu and his wife of "bribery and fraud" and "obstructing justice" at the end of another investigation into the case known as "File 4000". Netanyahu has been accused of providing regulatory concessions to the main partner and shareholder of the Bezeq Group, and the Walla news website, Shaul Elovic, in return for giving him and his family privileged media coverage between 2012 and 2017. This is the third case in which Netanyahu faces charges of corruption, although the prosecution has not yet formally charged him with any of them, as the investigation is ongoing.
