Within hours of 97 Liverpool fans being crushed to death at an FA Cup semi-final at Hillsborough, a story was already circulating: that the fans had done it to themselves. Four days later, The Sun printed an infamous front page - "The Truth" - and a lie that would last 27 years was set in stone. So where did that story come from, and how did it survive decade after decade of official scrutiny?

Andy and Neil are joined by LBC presenter Shelagh Fogarty, who was a journalistic apprentice in Liverpool in April 1989. She describes the day itself: the hundreds of Liverpool families who set off across the Pennines with no way of knowing whether the people they loved were alive or dead, and the furious supporters who made it home and went on the airwaves in an attempt to stop the smear campaign against them.

Together they unpick how the cover-up began almost immediately, who gained from it, and the role the media played in carrying it. They examine the case of David Duckenfield, the newly promoted Chief Superintendent commanding his first big match, and why families believe the system failed to hold anyone to account. They also ask what the disaster changed in football, in policing, and in how the British state behaves when it's caught in a lie. Ninety-seven people were unlawfully killed. Nobody has ever been convicted. Was this the biggest police cover-up in British history?
