The threat posed by Islamist militants to Britain is expected to remain high for the next two years and could even rise, the interior ministry said on Sunday, on the first anniversary of an attack that killed eight people in central London.
The current threat level to Britain is assessed as severe, meaning an attack is highly likely. The government said it had foiled 25 Islamist militant plots since June 2013 – 12 of those since March 2017 – and was currently handling over 500 live operations.
