A new system to alert the British public over threats from al Qaida and other terror groups is to be introduced in Britain, it was reported here Sunday. 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, the Sunday Telegraph and the Sunday Times newspapers said. Home Secretary John Reid is set to unveil the changes as part of a package of announcements early next week. Warnings are to be published on the websites of the Home Office and the domestic Intelligence service, MI5. The papers added that they will be divided into five separate levels, although not colour-coded as they are in the US.The UK currently has a seven-tier system based on descriptions of threats such as "substantial", which are not published. As well as dealing with the threat level system, 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.
