In his first conference speech as prime minister, Keir Starmer vowed that a Hillsborough law will be introduced in April, before the next anniversary of the football stadium disaster. The law will force public bodies to cooperate with investigations into future disasters and scandals.
This announcement follows a long campaign by the families of the 97 people killed (and hundreds more injured) when part of Hillsborough stadium collapsed in 1989.
The disaster and the inquiry that followed highlighted how justice is so often impeded by the tendency of powerful people to cover up information or refuse to cooperate in investigations.
