Case 1000: Cigars, pink champagne and tickets to see Mariah Carey
This investigation centres on illegal gifts allegedly received by the Netanyahu family — including pink champagne, jewellery, Cuban cigars and even tickets to a Mariah Carey concert — in exchange for political favours to billionaires.
In total, Netanyahu, wife Sara and son Yair are accused of receiving gifts worth more than US$280,000 ($410,740) in return for the Prime Minister promoting policies that benefited powerful allies.
Police say these allies — including Israeli-born Hollywood producer Arnon Milchan and Australian investor James Packer — received Netanyahu's political backing on key issues. For example, the Prime Minister pushed for a law, which the media labelled the "Milchan law", that cut taxes for Israelis returning to their homeland after living abroad.
Netanyahu has denied the allegations, while the billionaires have said their gifts were not intended as bribes. Police have said there is enough evidence to build a case against Milchan, the producer of films such as The Revenant, Fight Club and Pretty Woman, for bribery.
In his letter, Mandelblit said Netanyahu should be charged with fraud and breach of trust in connection with Case 1000.
Case 2000: A newspaper rivalry involving Adelson
Netanyahu is also accused of using his connections to Adelson, the US casino magnate and an ally of the Israeli leader, to push a newspaper owner for more favourable coverage of his Government.
A quid pro quo agreement was allegedly negotiated with Arnon Mozes, publisher of Yedioth Ahronoth, a major Israeli daily newspaper. Under the alleged deal, Mozes would have eased off his paper's critical coverage of the Israeli Prime Minister in return for Netanyahu pushing Adelson to limit the circulation of Israel Hayom, a free newspaper owned by the American billionaire.
A leaked transcript of Netanyahu's conversation with Mozes was picked up by Israeli media in 2017.
"Every day I have somebody who is killing me," the Prime Minister complains, according to media reports, before asking Mozes "to lower the level of hostility toward me from 9.5 to 7.5".
Netanyahu later said that his offer to Mozes wasn't serious. Adelson told investigators that he was not aware of any agreement between Netanyahu and Mozes and was angered by the idea.
Case 4000: A favour for a telecom giant
Netanyahu is accused of offering regulatory favours to one of Israel's largest telecommunications companies in return for positive coverage of the Prime Minister and his wife on a popular news site owned by the company.
Netanyahu, who served as Israel's Communications Minister between 2014 and 2017 in addition to being Prime Minister, is alleged to have used his influence to help the Bezeq group and its owner, Shaul Elovitch. Elovitch, a close friend of the Israeli leader, is alleged to have ordered the Walla News site to provide more favourable coverage of the Netanyahus in return.
"Netanyahu and his associates intervened in a blatant and ongoing manner, sometimes even daily, in the content published by the Walla News website and sought to influence the appointment of senior employees [editors and reporters]," police said in a statement released in December.
Netanyahu has denied the allegations.
