Footage of transgender activists clashing with police at a rally held by Kellie-Jay Keen (aka Posie Parker) this afternoon (April 30). Many used umbrellas and wore masks to hide their identities.

Posie was speaking to a crowd of supporters in Hyde Park, London. Posie Parker is British anti-transgender rights activist and founder of the group Standing For Women. She describes herself as a women's rights activist.

Keen-Minshull opposes laws and policies that allow transgender people to be legally recognised as their gender, the use of public bathrooms by transgender people according to their gender, the participation of transgender people in sports that align with their gender, and drag performances, including in locations that may be viewed by children.
