Members of Parliament are expected to approve the long-delayed Hillsborough Act

Sir Kiir’s expected successor, Andy Burnham, said the debate would be a “very emotional time”. Both men are expected to speak in the Commons later.

The proposed law took its name from the The 1989 Hillsborough disaster that killed 97 people during the FA Cup semi-final between Liverpool and Nottingham Forest at Sheffield Wednesday.

Police chiefs have been found spreading lies about the crash, blaming Liverpool fans and hiding evidence of their own failings.

The legislation, which promises to provide legal aid to people affected by accidental or government-related deaths, was a promise in Labour’s 2024 general election manifesto. Officially known as the Public Office (Accountability) Bill.

Sir Kerr has promised to pass the bill on 15 April 2025 to mark the 36th anniversary of the Hillsborough disaster.

But this deadline was missed and the government abandoned the final debate in January Following protests by campaigners and some Labor MPs.

This happened after the government reform teamed up with intelligence officers and got the approval of their service chief.

Families of the dead said MI5 and MI6 officers should be fully compliant with the proposed law and pointed to a series of cases where MI5 had given false information. Including the 2017 Manchester Arena bombing.

The government has now proposed amendments to the law which campaigners say will leave the spy agency with no independence and which ministers believe will not harm national security.

These will be considered during the report of the bill before it is approved at third reading on Tuesday.

The bill goes to the House of Lords, where it is subject to further changes, including by peers concerned about its impact on national security.

On Tuesday, Downing Street said the government wants the legislation to be on the statute books in time for the next anniversary in April next year.

Ahead of the debate, Sir Kerr said the “popular law” was “a tribute to the incredible families and campaigners who have fought for decades and decades to get justice for their loved ones”.

“They suffered unimaginable grief and never gave up. Without their commitment to God, the Hillsborough Act would never have happened,” he added.

In a debate on the bill in November last year, Sir Keir highlighted that Hillsborough was not an isolated example of state coverage.

It has also sparked scandals linked to other scandals, including the Grenfell Tower fire, tainted blood and gangs.

Burnham, who is in the running to replace Sir Kier as prime minister on July 20, said the Hillsborough families had “shown extraordinary courage” and were “helping to reshape the relationship between public and government for generations to come”.

He said: “Hillsborough’s teaching goes beyond promoting the duty of honesty.

“It asks us what kind of country we want to be, where power is concentrated in distant institutions or where it is shared more equitably with the people and where the institutions are designed to serve.

“If an entire city has been ignored for two decades speaking the truth about the deaths of its people, what other communities have gone unheard? Which voice has been forgotten simply because it has lost power?”

Labour’s Makerfield MP said: “I believe in the need to build a Britain where every community is treated equally and no one is unfairly left alone.”

Hillsborough law campaigners, including those whose family members were killed in 1989, welcomed the bill’s return to the Commons.

In a statement, Charlotte Hennessy, Sue Roberts, Steve Kelly and Margaret Aspinall said: “It’s encouraging to know that this is not just about legislation, but about the treatment of victims and survivors and changing culture, which will protect others forever.”
