One of Israeli Prime Minister Benjamin Netanyahu's closest confidants has agreed to testify against him in a graft probe, Israeli police said Wednesday, in a fresh threat to his long tenure.
Two new corruption investigations announced this week, hot on the heels of a police recommendation that Netanyahu face charges in two other cases, have fuelled growing speculation he could be forced to step down or call an early election.
Shlomo Filber, a Netanyahu ally for more than 20 years and former director general of the communications ministry, is expected to agree to turn state witness in exchange for avoiding jail, according to Israeli media reports confirmed by police.
A gag order prevented publishing any details of the deal.
Filber was arrested on Sunday in connection with allegations that Shaul Elovitch, the controlling shareholder of Israeli telecommunications giant Bezeq, gave Netanyahu positive coverage on his Walla! news site in exchange for policies benefiting the business.
Filber is suspected of mediating between Netanyahu and Elovitch and promoting regulatory changes worth millions to Bezeq.
Two senior Bezeq employees also detained on Sunday, CEO Stella Handler and Amikam Shorer, appeared Wednesday in court, where their remand was extended until February 26.
The prime minister himself has not been named as a suspect in the investigation.
In another case announced this week, two Netanyahu allies are alleged to have offered a judge promotion in exchange for dropping a case against the premier's wife.
The two men have been identified as Nir Hefetz and Eli Kamir, both former media advisers for the Netanyahu family.
Their alleged offer was to Hila Gerstel, a judge involved in a graft probe into Sara Netanyahu over alleged misuse of public funds.
Additionally last week police said there were grounds to indict the prime minister himself in two other cases for bribery, fraud and breach of public trust.
Netanyahu, 68, has rejected all the allegations, and released a new video on his Facebook page late Tuesday strongly denying any wrongdoing.
In an address to American Jewish leaders in Jerusalem late on Wednesday, an upbeat Netanyahu ignored his legal woes, expounding instead on Israel's success in diplomacy and technology while reiterating his position on the danger Iran posed to the Jewish state.
"We will never allow Iran to establish military bases in Syria to be used against us (and) we will never allow Iran to get nuclear weapons," he said.
While Netanyahu's coalition partners have so far said they will stand by him, they have remained largely silent since Sunday.
His right-wing Likud party, the largest in parliament, still remains supportive, but the opposition has repeatedly called for him to step aside.
Polls last week showed the Israeli public was split on the prime minister's future.
"If Shlomo (Momo) Filber indeed signed a state's witness agreement last night, it is the end of an era," Ben Caspit wrote in the Maariv newspaper Wednesday, calling him Netanyahu's "closest and most intimate covert operations officer".
"Always in the shadows, always loyal, efficient, secretive and ideological, Bibi (Netanyahu) knew that he could count on Momo. Until yesterday," said Caspit, the author of a recent book on the prime minister.
In his Facebook video Tuesday night, Netanyahu again accused the media and police of a witch-hunt.
Quoting a biblical phrase referring to the ancient Egyptians' treatment of the Jews, he said "the more they were oppressed, the more they multiplied and spread," showing a current television poll predicting a rise in the number of his seats his Likud party would win in an election.
Filber is seen as one of the architects of Netanyahu's surprise 2015 election victory, after which he was appointed to head the communications ministry.
The next election is not due until the end of 2019 but Israeli media speculated Netanyahu might call go the polls before the end of this year.
Under the headline "The smell of elections", the pro-Netanyahu newspaper Israel Hayom published a poll suggesting he might even increase his support in parliament despite the allegations hanging over him.
His Likud party currently holds
