For the past year I’ve been posing as Dan Jones - a member of the far-right group Patriotic Alternative (PA).
I’ve attended protests, a summer camp filled with families, a secretive conference, and when I told them I was sofa-surfing, the group even found me a job.
What I heard while undercover was talk of race wars, threats of violence against migrants, and people planning to arm themselves.
The evidence I secretly filmed has led to calls for a police investigation, and separate calls to change the law and ban the group.
