A proposed 'Hillsborough Law' is to be presented to parliament today in the hope of forcing public bodies to tell the truth in legal proceedings.
The Public Authority (Accountability) Bill is to be introduced by Labour MP Andy Burnham and if brought in would require employees of public bodies, such as police forces, to act with 'transparency, candour and frankness' during legal proceedings.
If it eventually gets the green light, those who breach the law will face jail.
The bill was drafted in the wake of the conclusion of the Hillsborough inquests, which ruled that 96 football fans who died after a crush on the terraces at Hillsborough football stadium in 1989, were unlawfully killed and that police failings played a part.
Police officers attempted to cover up the failings of South Yorkshire Police over the years in a bid to shift blame for the disaster onto the fans.
The bill also seeks financial support for families involved in inquests involving a public body.
