The government is likely to reject calls for a public inquiry into the 7 July bomb attacks on London.
Ministers will instead publish a definitive account of what happened, the BBC has learned.
The account would include material gathered from intelligence agencies and evidence compiled by police.
The absence of a wider public inquiry is likely to anger Muslim community groups, who argue that it is essential to understanding what happened.
After the bombings there were calls for a public inquiry and, in September, the home secretary said it had not been ruled out.
But ministers felt it would divert attention and resources away from pressing security and community issues and take too long.
The government has acknowledged, however, that the public requires a complete picture about the events of 7 July and details about the four men who carried out the attacks.
The remit of the inquests into their deaths does not extend that far and the information will not emerge at a criminal trial - because there will not be one as the bombers are dead.
Instead, a senior civil servant will compile a narrative, drawing together intelligence and police material.
It is expected that the document will be submitted for publication to two Parliamentary committees which are conducting their own inquiries.
The attacks by four suicide bombers on three Tube trains and a bus killed 52 people and injured hundreds.
