JERUSALEM (Reuters) - Israeli Prime Minister Benjamin Netanyahu faced calls to resign over a corruption scandal on Friday, as senior government colleagues publicly declared support after some signs of cracks in party loyalty.
Netanyahu said he would not step down after he was indicted on charges of bribery, fraud and breach of trust by Israel's attorney-general on Thursday night.
The 70-year-old conservative Likud party leader denies all wrongdoing and denounced the indictment - the first against a sitting Israeli prime minister - as an "attempted coup".
But his ability to lead a country mired in political crisis, after two inconclusive elections this year that failed to produce a government, is being questioned.
The centrist Blue and White Party headed by Netanyahu’s main rival, Benny Gantz, issued a statement calling on him to "immediately resign from all ministerial positions in the government".
The party - which has 33 of parliament's 120 seats to Likud’s 32 - said its lawyers had formally approached the prime minister and attorney general’s offices saying it was "imperative" that Netanyahu step down.
A poll aired by Israel's Channel 13 TV found that 56% of Israelis believe Netanyahu cannot continue to govern after being indicted. A total of 35% said he can and 9% were undecided.
Under Israeli law, he is under no obligation step down a prime minister. But with Israel heading towards a likely third election in less than a year, Netanyahu could soon find himself in the difficult position of trying to win an election while preparing to be prosecuted.
The support of his Likud party colleagues is likely to be crucial to Netanyahu's chances of staying in power.
RULING PARTY CREAKS
Two Likud lawmakers publicly broached holding a party leadership contest on Thursday, but even such mild expressions of disloyalty upset loyalists.
Senior ministers issued public statements declaring their support, and Justice Minister Amir Ohana said he was proud of his fellow Likud parliamentarians for standing by Netanyahu, adding pointedly: "Except for two of them."
Netanyahu’s ultra-nationalist coalition partner Bezalel Smotrich, the transport minister, also offered sympathy for Netanyahu over the charges against him, announced by Attorney-General Avichai Mandelblit on Thursday.
Smotrich said in a tweet that planned street protests in support of the prime minister were aimed at preventing "a predatory, violent and dangerous judicial dictatorship".
After a national televised address on Thursday night, Netanyahu himself kept a low profile on Friday, posting a tweet with heart and an Israeli flag emojis saying: "Thank you for your support and love. Shabbat Shalom." He later issued a video message undertaking to accept the court ruling in his case.
But Israel's election schedule could work against Netanyahu, Israel's longest serving prime minister after 10 successive years in power plus three years in office in the 1990s.
President Reuven Rivlin on Thursday set a three-week deadline for lawmakers to nominate a new candidate from their own ranks to try to form a new government after Netanyahu and Gantz both failed to do after April and September elections.
If that also fails to produce a government, an election will be triggered in three months.
A source close to Rivlin said he expected appeals to disqualify Netanyahu as a candidate because of the indictment. If the president does so, Netanyahu could be ejected by Likud.
"Netanyahu's great fear is that, amid the extraordinary constitutional crisis that has been created, and amid the political and legal synchronisation, he will emerge as the only member of parliament who cannot do this (form a government)," wrote Tal Shalev, political commentator for Israel's Walla news site.
Two of the three legal cases against Netanyahu involve accusations that he offered media bosses inducements in return for more favourable coverage of his policies and personal conduct. He has dismissed the accusations.
