The Security Service MI5 will announce tomorrow that subscribers to its website can sign up for email notification of changes to the current threat level.

A spokeswoman for the Home Office said: "There will be two electronic lists, one for people interested in updates to the threat level and one for changes and updates to the website. This aims to improve public understanding of the service's work and to offer faster information about threat levels." Anyone can sign up to the lists.

REASSURING!
