Home secretary, Priti Patel, has announced the reduction of the UK’s terrorism threat level from "severe" to "substantial", but has warned that attacks are still “likely”.
In a written statement to parliament on Monday (February 08), Patel said the Joint Terrorism Analysis Center (JTAC) had lowered the UK’s terror threat level due to “the significant reduction in the momentum of attacks in Europe since those seen between September and November” last year.
There are five terror threat levels in total including “Low”, “Moderate”, “Substantial”, “Severe”, and “Critical”, indicating escalatory levels of risk.
Despite the reduced threat level, the Home Secretary pleaded for help from ordinary people by saying that “the public should continue to remain vigilant and report any concerns to the police”.
"Terrorism remains one of the most direct and immediate risks to our national security", Patel added.
JTAC – which determines the terror threat level based on a wide range of intelligence and open source information – is based inside the headquarters of the Security Service (MI5) at Thames House in London.
JTAC staff is mostly made up of people from policing, counter-terrorism, security and broader governmental backgrounds.
The terror threat level was moved up to “severe” from “substantial” last November following terrorist attacks in France and Austria.
The highest level, “critical”, was last reached in September 2017, following the Parsons Green train bombing.
