Israeli prime minister Benjamin Netanyahu should be charged with bribery and fraud, police have said.
There was, however, insufficient evidence to charge Mr Netanyanu's son Yair, police said.
Netanyahu served as communications minister from 2015 to 2017.
But Netanyahu may want to seek a renewed mandate from the people, forcing a prosecutor to think twice before indicting him.
Shortly after the police recommendations were made public, Netanyahu issued a statement saying that the allegations had no legal basis and that ultimately nothing would come of the investigation.
Police said they have enough evidence to show Netanyahu and his wife Sara accepted bribes and committed fraud and breach of trust. Elovitch, in return, ordered Bezeq Group's Walla news to provide favourable coverage for Netanyahu and his wife Sara Netanyahu.More news: Ukraine closes border to Russian men of combat age, citing invasion fears
Bezeq telecom company's controlling shareholder Shaul Elovitch, seen here in a Tel Aviv courtroom on February 22, 2018, is suspected of involvement in a scandal in which Israeli Prime Minister Benjamin Netanyahu allegedly advanced regulatory decisions as communications minister that benefited Bezeq, in exchange for positive coverage on the company's Walla news site.
The final decision on whether to indict rests with Israel's attorney-general, who is still weighing whether to charge Netanyahu in the other two cases.
Police recommended that Bezeq's former chairman, Shaul Elovitch, who was forced to step down earlier this year, stand trial for giving bribes. Both Netanyahu and Mozes have said they were not serious discussions; rather, they each claim they were trying to expose the other's lack of trustworthiness.
In the second case, Mr Netanyahu is suspected of receiving gifts worth at least a million shekels ($270,000; £210,000) from Hollywood mogul Arnon Milchan and other supporters. Netanyahu held the government's communications portfolio until previous year and oversaw regulation in the field.
"A prime minister with so many corruption cases around him can not continue at his job and must resign", Gabbay tweeted.
Israeli investigators said they had amassed more evidence that the prime minister traded influence for favors, this time in a case involving the country's largest telecommunications carrier.
