Ex-Israeli president Moshe Katsav has been jailed for seven years after being convicted of rape and other sexual offences against three female former employees.
He broke down in tears after sentencing and screamed at the judges: "You made a mistake! It is a lie! The girls know it is a lie."
As he left the courtroom in Tel Aviv, two of his grown-up sons scuffled with security guards.
Katsav then shouted at the guards: "I saw you. You hurt my boy."
The 65-year-old was charged with twice raping an aide when he was a cabinet minister in the late 1990s.
And he was also accused of molesting or sexually harassing two other women who worked for him during his time as president between 2000 and 2007.
The politician denied all the allegations - but a three-judge panel found him guilty in December and said his testimony had been "riddled with lies".
They said: "When a woman says no, she means no."
The former president was also convicted of obstructing justice, for trying to talk to one complainant about her evidence to police.
He is the highest-ranking Israeli official ever to be sent to prison.
Sentencing the politician, the court accused him of exploiting his position to become a sexual offender.
t also ordered him to report to prison on May 8, giving him time to prepare an appeal. He must also pay fines of about $25,000 (£15,000) and $7,000 (£4,000) to two of the women.
Katsav claimed he was the victim of extortion and an ethnically-motivated "witch hunt".
He suggested he was targeted because he is a Sephardic Jew - a Jew of Middle Eastern origin.
The case, which has brought shame to Israel's highest office, went to trial after he rejected a plea bargain that would have kept him out of jail.
Prime Minister Benjamin Netanyahu described his conviction as "a sad day for Israel and its residents".
He said the verdict showed that "all are equal before the law" and one newspaper called it an "earthquake".
The conviction was welcomed by women's groups that have long complained of lenient attitudes to sexual harassment in the workplace.
The case began nearly five years ago when he complained that a female employee was trying to extort him.
She went to police with her side of the story, and other women came forward with similar complaints of sexual assaults.
Israel's parliament elected him president in a surprise victory over Shimon Peres, the Nobel Peace Prize-winning elder statesman.
Mr Peres succeeded Katsav as president, an appointment observers say has restored dignity to the post.
