The UK’s terrorism threat level has been lowered from “severe” to “substantial” after fewer attacks in Europe.
Home Secretary Priti Patel said there had been a “significant reduction” in the threat level since a string of attacks in Europe between September and November.
However, Ms Patel said the public should remain vigilant because a "substantial" threat level meant a terror attack was still likely.
"Terrorism remains one of the most direct and immediate risks to our national security,” she said.
“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."
"Severe" is the second-highest of five levels and indicates an attack is "highly likely".
Britain raised the threat level from "substantial" to "severe" at the start of November after four people were killed and dozens wounded in a shooting rampage in Vienna the night before the city went into coronavirus lockdown.
Police in the Austrian capital said the attack was carried out by an extremist who had spent time in prison.
In October, three people were killed in knife attacks in the southern French city of Nice.
It came after an extremist beheaded a teacher in Paris after he showed pupils a caricature of the Prophet Mohammed.
The UK threat level was briefly raised to "critical", the maximum level to indicate an attack is "highly likely in the near future", in May and September 2017.
The moves were in response to conflicts in Syria and Iraq. In the same year extremists carried out attacks in Manchester and London.
It was also raised to "critical" in August 2006 after the security services said they foiled a plot to blow up flights between Britain and the US.
The decision to lower the UK’s threat level was made by the Joint Terrorism Analysis Centre on Thursday last week, Ms Patel said.
The threat level from Northern Ireland-related extremism in the region remains "severe", according to the UK's domestic intelligence service, MI5.
