Jimmy Savile was a "callous, opportunistic, wicked predator" who abused people who had a right to be safe, Health Secretary Jeremy Hunt said.
Victims were let down as "people and institutions turned a blind eye" to Savile's crimes, Hunt said.
Hunt said the whole country will share a "deep sense of revulsion" at the details of Savile's crimes.
"He was a sickening and prolific sexual abuser who repeatedly exploited the trust of a nation for his own vile purposes," Hunt told MPs as he apologised on behalf of the government and NHS.
Chilling reports reveal Jimmy Savile committed "truly awful" abuse against patients at hospitals and boasted about having sex with corpses.
Investigators are pretty sure the scale of abuse by disgraced presenter Jimmy Savile at NHS hospitals has been under-reported.
