Hillsborough: Undermined evidence was true, BBC Panorama finds

An investigation by the BBC's Panorama into the cover-up that followed the Hillsborough disaster has revealed crucial evidence from an off-duty police officer, which was undermined at the original inquest into the tragedy, was true.

The officer's account would have challenged a controversial decision by the coroner to set a time limit beyond which dying fans could not have survived.

Peter Marshall reports.

The Panorama one hour special - Hillsborough: How They Buried the Truth - will be shown on BBC One at 21:00 BST on Monday 20 May. Or catch up later on BBC iPlayer.
