Meet the 25-year old Swede who went undercover to expose the alt-right

Patrik Hermansson, long-time contributor to Expo, spent a year undercover in the British branch of the alt-right movement, on a mission from the anti-fascist organisation Hope not Hate.
The journey took him deep into the heart of the movement – and to the United States.
The result is the most comprehensive report ever on the alt-right movement.
