Israel's attorney-general indicted Benjamin Netanyahu on a range of corruption charges Thursday, the Justice Ministry announced, potentially spelling an end to the Prime Minister's decades-long political career.

Attorney-General Avichai Mandelblit "decided to file charges against the Prime Minister Benjamin Netanyahu for offences of receiving a bribe, fraud, and breach of trust," a ministry statement said.

It said a note of the decision and a copy of the charges had been provided to the premier's lawyers.

Netanyahu, who strongly denies all the charges, becomes the first Israeli prime minister to be indicted while in office.

Mandelblit is due to give a public statement at 1730 GMT, with Netanyahu expected to respond.

Netanyahu is not legally required to resign, only if convicted with all appeals exhausted, but political pressure is likely to be intense.

Netanyahu may now ask the Israeli parliament, or Knesset, to grant him immunity from prosecution.

Rightwinger Netanyahu, who has been in power since 2009, is Israel's longest-serving prime minister and dominates the country's political scene.

The decision comes as Netanayhu, a close ally of US President Donald Trump, is fighting for his political life.

Israeli being without a government for nearly a year, with neither Netanyahu nor his centrist rival Benny Gantz able to form a coalition government following deadlocked elections in April and September. (AFP)
