A new system to alert the public over threats from al Qaida and other terror groups is to be introduced in Britain.
Although the Home Office will not reveal details of how it will operate, it is understood that the new system will be simpler than the one it will replace.
Home Secretary John Reid is set to unveil the changes as part of a pack-age of announcements early next week.
Two Sunday newspapers reported that warnings are to be published on the websites of the Home Office and MI5.
One paper added that they will be divided into five separate levels, although not colour-coded as they are in the US.
America's Department of Homeland Security operates a five-level public w arning system with colour-based alerts ranging from green to red, the highest state of alert.
The UK currently has a seven-tier system based on descriptions of threats such as "substantial", which are not published.
In May, the cross-party Intelligence and Security Committee (ISC) called for a more transparent threat level and alert system in the UK in its report on the July 7 bombings.
The committee high-lighted how the threat level had been reduced from "severe general" to "substantial" prior to London attacks, but said that the decision was "not unreasonable" on the basis o f the intelligence available.
It said: "The aim is to bring clarity to both security practitioners and the general public without causing alarm."
Three separate documents dealing with terror-ism are expected to be unveiled by the Government next week.
As well as dealing with the threat level system, Dr Reid is expected to publish a wide-ranging summary of the Government's long-term terrorism strategy code-named "Contest".
The announcement is expected to set out efforts to prevent terrorism, pursue terrorists, protect the public and prepare for the possibility of terrorist attacks.
A third document is also set to be published by the Department for Communities and Local Government on preventing extremism.
Meanwhile, Ministers were accused of being "in denial" over the future of ID cards as leaked emails suggested hitches in plans to roll out the Govern-ment's flagship scheme.
The exchanges between senior civil servants reveal that ministers are "rethinking" the entire scheme and have planned a "face-saving" compromise. ..SUPL:
