THE Prime Minister has missed his own deadline to introduce a law obliging public authorities and officials to fully co-operate with official inquiries.

The Hillsborough Law, promised ahead of the disaster’s 36th anniversary today, was expected to introduce a “duty of candour” requiring proactive co-operation with official investigations.

Campaigners are also understood to be concerned over precisely to whom the law will apply.

Elkan Abrahamson, director of the Hillsborough Law Now campaign said: “We remain largely in the dark as to the status of the Bill and the next steps.

“The recent Cabinet Office redraft of the Bill is a betrayal of the promises made by the government so there must be urgent steps to return to the original principles.

“We have made it clear to the government that we will not accept anything that falls short of a full Hillsborough Law which includes a duty of candour for all public officials.”

On X, Sir Keir wrote: “I promised to bring a Hillsborough Law before Parliament, with a legal duty of candour for public authorities and public servants, and criminal sanctions for anyone who fails to comply.

“I will deliver on that promise.”
