Theresa May announces the threat level has been raised from “severe” to “critical“, meaning an attack “is expected imminently“. Armed military personnel are being deployed to assist the police. The army will replace the police at some key sites and events. First time since 2007 the threat level has been at critical…

PM statement:

“This morning, I said that the Joint Terrorism Analysis Centre – the independent organisation responsible for setting the threat level on the basis of the intelligence available – was keeping the threat level under constant review.

 

It has now concluded, on the basis of today’s investigations, that the threat level should be increased, for the time being, from SEVERE to CRITICAL.  This means that their assessment is not only that an attack remains highly likely, but that a further attack may be imminent.

 

The change in the threat level means that there will be additional resources and support made available to the police as they work to keep us all safe.

 

As a result of the JTAC’s decision, the police have asked for authorisation from the Secretary of State for Defence to deploy a number of armed military personnel in support of their armed officers.  This request is part of a well-established plan, known as Operation TEMPERER, in which both the armed forces and the police officers involved are well-trained and well-prepared to work in this kind of environment.  The Secretary of State for Defence has approved this request, and Operation TEMPERER is now in force.

 

This means that armed police officers responsible for duties such as guarding key sites will be replaced by members of the armed forces, which will allow the police to significantly increase the number of armed officers on patrol in key locations.  You might also see military personnel deployed at certain events, such as concerts and sports matches, helping the police to keep the public safe.  In all circumstances, members of the armed forces who are deployed in this way will be under the command of police officers.

 

Precisely how the military and armed police officers will be deployed is an operational decision for police commanders, and Assistant Commissioner Mark Rowley of the Metropolitan Police will be making a statement giving further details at New Scotland Yard later this evening.

 

In the coming days and weeks, there will of course be many events hosted up and down the country.  The police will work with the organisers and hosts of these events, to come to a judgement about how they can go ahead while making sure the people who attend them are safe and secure.

 

I do not want the public to feel unduly alarmed.  We have faced a serious terrorist threat in our country for many years.  And the operational response I have just outlined is a proportionate and sensible response to the threat that our security experts judge we face.  I ask everybody to be vigilant, and to cooperate with and support the police as they go about their important work.”
