‘I have a lot of resentment’: Patrisse Cullors on co-founding Black Lives Matter, the backlash – and why the police must go

It is 10 years since she helped launch possibly the biggest global protest movement in history. But then came controversy as huge sums of money flowed in. She describes how her childhood inspired her activism - and the hurt she has suffered

You're gonna make me cry," Patrisse Cullors warns when I ask how she feels about being criticised by other Black people. Then the co-founder of Black Lives Matter (BLM) turns away from the webcam and starts to sob, hand to her mouth. I'm crying because I was prepared for rightwing attacks. I wasn't prepared for Black people to attack me. And I think that's probably the hardest thing in this position, to lose your own people. The people that you love the most, the people that you do this work for. The human being feels betrayed, the leader feels like: Yeah, welcome to Black leadership. This is the fucking hazing.'"

It's almost 10 years since Cullors, 38, helped to launch what has been described as the largest global protest movement in history. In that time she has gone from local community organiser to international activism A-lister. But with celebrity has come controversy, including complaints about a lack of transparency about the huge sums of money that have flowed BLM's way. She has also been called a hypocrite for amassing a property portfolio inconsistent with her beliefs as a self-described trained Marxist." She has called these attacks: Not just a character assassination campaign, but a campaign to actually get me assassinated."
