Members of the public should always remain alert to the danger of terrorism and report any suspicious activity to the police on 999 or the anti-terrorist hotline: 0800 789 321. If your information does not relate to an imminent threat, you can also contact M15.
Threat levels refer to a system used to assess and communicate the degree of danger or risk posed by a particular threat, such as terrorism or natural disasters. These levels are typically represented by a scale, providing individuals and organizations with a standardized understanding of the severity and potential impact of a threat in order to make informed decisions and take appropriate actions.
The threat to the UK (England, Scotland, and Northern Ireland) from terrorism is SUBSTANTIAL.
