Incel ideology: a new blurry form of extremism incubated online

Analysis: The Plymouth shootings heralded a new type of terrorist threat, but what hasn't changed is the socially isolated individuals behind it

For several years, those whose job description includes making the nation safe from terrorism have been documenting something novel and quite chaotic. Thursday's murderous rampage on the streets of Plymouth merely confirmed the new terror threat has arrived.

The traditional silos of far right and Islamist extremism are disappearing. Instead, the security services are monitoring individuals who have gone for a mixed approach to extremist ideologies, able to accommodate the views of Tommy Robinson alongside Osama bin Laden, often adding a layer of conspiracy theory and fantastical tropes for good measure. Individuals who jump casually between fascist dogma, Islamism or misogyny are increasingly cropping up on the radar of intelligence agencies.
