The decision to change the threat level is taken by JTAC independently of Ministers. JTAC conducts a formal review of the terrorism threat level every six months.
This is a systematic, comprehensive and rigorous process, based on the very latest intelligence and analysis of internal and external factors which drive the threat.
Despite the change in the threat level, 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 might well occur without further warning.
As ever, the public should remain vigilant and report any concerns they may have to the police.
Government, police and intelligence agencies will continue to work tirelessly to address the threat posed by terrorism in all its forms. The threat level is kept under constant review.
