Britain downgrades al-Qaida terror attack alert level

Officials reduce assessment of threat from 'severe' to 'substantial', its lowest level since 9/11

The official assessment of the threat level of an al-Qaida terrorist attack on Britain has been lowered from "severe" – where an attack is deemed highly likely – to "substantial", where an attack is considered a strong possibility.

The decision to lower the official threat level follows a new assessment by MI5 and the joint terrorism analysis centre, based on intelligence gathered in Britain and abroad on how close terrorist groups may be to staging an attack.

The designation of a "substantial" threat level is the lowest since 9/11. It confirms that the swine flu pandemic is now a bigger threat to the life of the nation than terrorism.

The home secretary, Alan Johnson, acknowledged that fact on Sunday, when he told the BBC's Andrew Marr programme that swine flu came "above terrorism as a threat to this country". He said the long-term preparations had involved the whole "Cobra machinery", a reference to the Cabinet's emergency committe that handles major disasters.

The decision reportedly follows an official assessment of Operation Pathway, one of MI5's biggest counterterrorism campaigns, which led to the arrest of 11 Pakistani men in April. All those arrested were released without charge, and no explosives or weapons were found.

The system of threat levels is made up of five stages. At "critical", an attack is expected imminently. At "severe", an attack is regarded as highly likely. At "substantial", an attack is a strong possibility. At "moderate" an attack is possible but not likely. And at "low", an attack is deemed unlikely.

The home secretary said in a statement: "We still face a real and serious threat from terrorists and the public will notice little difference in the security measures that are in place, and I urge the public to remain vigilant. The police and security services are continuing in their thorough efforts to discover, track and disrupt terrorist activity."
