The deputy Prime Minister, Nick Clegg, is backing the campaign to get all documents, relating to the 1989 disaster at Sheffield's Hillsborough stadium, published.
Since Mr Clegg heads the Cabinet Office, which was opposing publication, his intervention suggests that the Government has accepted the inevitable.
Although more than 22 years have passed since 96 Liverpool fans were killed in the crush, the issue is still a potent one.
Nearly 130,000 people have signed an e-petition on the Downing Street website demanding that all relevant documents be made public.
Twitter messages from Liverpool manager, Kenny Dalglish, and Newcastle United player, Joey Barton, provided support.
When the Information Commissioner, Christopher Graham, ruled that the papers should be published, the Cabinet Office appealed, on the grounds that it was for the Hillsborough Independent Panel set up last year to decide how much of the 45,000 boxes of material should be public.
Yesterday the Government confirmed that the issue has been passed to the Commons Backbench Business committee with a view to having a debate on it.
