Vegan chef, skateboarder and stunt performer Mathew Pritchard, known for his brand Dirty Vegan and his role on TV show Dirty Sanchez, eats a ''yoghurt'' with fake blood and guts in Leicester Square, as part of a stunt organised by animal rights group Viva! to raise awareness of the conditions at zero-grazing dairy farms where cows are kept, which they say supply products to major dairy companies Muller and Arla.
