The UK’s terrorism threat level has been reduced from “severe” to “substantial” due to a significant reduction in the momentum of attacks in Europe.

Home Secretary Priti Patel told MPs the lowered threat level still meant an attack on the UK remained “likely” and the public should remain vigilant.

The threat level was raised to severe by the Joint Terrorism Analysis Centre (JTAC) in November following Islamist attacks in Austria and France.

But on Thursday last week the expert analysts reduced the level, Ms Patel told MPs on Monday.

“The decision to lower the threat level from severe to substantial is due to the significant reduction in the momentum of attacks in Europe since those seen between September and November 2020,” the Home Secretary said.

“However, the UK national threat level is kept under constant review and is subject to change at any time.

“Terrorism remains one of the most direct and immediate risks to our national security.

“Substantial continues to indicate a high level of threat; and an attack on the UK is still likely.

“The public should continue to remain vigilant and report any concerns to the police.”
