The UK intelligence and security agencies assess the threat from international terrorism in the UK as severe, meaning an attack is highly likely. This threat is predominantly driven by Daesh, which seeks to maintain its narrative of success despite military losses, and retains some territory. Daesh continues to prioritize and incite external attacks against the West through extremist propaganda. Since March 2017 there have been three successful terror attacks and several disrupted plots in the UK, reflecting a shift in the nature and scale of extremist attack planning. While Al-Qaeda also remains a threat, Daesh's extremist narrative has emerged as the main driver of radicalization and terrorism in the UK.
