Jimmy Savile scandal (2012)
A year after the BBC presenter's death, an ITV documentary revealed he had sexually abused hundreds of children over decades. Police later identified more than 200 victims ranging in age from five to 75.
Savile was never prosecuted, dying in 2011 at 84. The scandal triggered Operation Yewtree, which launched dozens of historic abuse prosecutions.
Historic child abuse allegations became far more likely to be investigated and prosecuted across the UK.
Shows how abuse by powerful public figures can stay hidden for decades, and how the post-Savile climate made prosecutions like Donaldson's possible.
