The long-delayed bill to create a Hillsborough Law is expected to be approved by MPs next week after the government confirmed it could return to Parliament before the summer recess.
Downing Street withdrew the legislation from the parliamentary agenda in January following disagreements over how far it would require intelligence services to comply with a proposed legal “duty of candour” on public bodies and officials.
The legislation – formally known as the Public Office (Accountability) Bill – is now expected to be passed by the House of Commons on Tuesday, paving the way for it to become law by the autumn.
The 1989 Hillsborough disaster claimed 97 lives after a crush during the FA Cup semi-final.
A government source has told the BBC that ministers have now agreed a new amendment, which campaigners say means there will be no exemption for the intelligence services.
Police spread false narratives blaming Liverpool fans, and withheld evidence of their own failings after the disaster at Sheffield Wednesday’s ground.
Fresh inquests held in 2016 found that the Liverpool fans had been unlawfully killed, and it was the police who had caused or contributed to their deaths.
The Hillsborough Law would create a legal duty for public officials to tell the truth to inquiries and investigations.
