Number of UK anti-migrant vigilante groups surges in last 18 months

Exclusive: Many use community protection as a cover for racist thuggery', raising concerns about fresh disorder

At least 28 anti-migrant vigilante groups have formed in the UK in the last 18 months, ranging from unauthorised street patrols claiming to protect women and children to groups harassing migrants in France and blocking ports.

From Belfast to the south coast of England, the number of active groups has surged since the summer of 2025, according to analysis by the Guardian, amid widespread concerns over fresh disorder after black-clad vigilantes, many of them wearing balaclavas, blocked roads in Portsmouth and Dover last weekend.
