Jimmy Savile, a BBC presenter and celebrity fundraiser who died in October 2011, was subsequently confirmed by Operation Yewtree (Metropolitan Police, 2012–2016) to have been one of the most prolific sexual offenders in British criminal history, with 450 formal complaints covering offences across BBC studios, NHS hospitals, Broadmoor psychiatric hospital, and Stoke Mandeville Hospital. The Dame Janet Smith Review (2016, commissioned by the BBC) found that senior BBC managers had received complaints about Savile over decades and had failed to act. The Kate Lampard NHS review (2015) documented similar failures across NHS trusts. The BBC's own Newsnight programme had prepared an investigation into Savile's offending in 2011 that was shelved by editors. This is a confirmed institutional cover-up across multiple British public institutions.
