The event - the most attended in its three-year history - was organized by vegan activist collective Surge and Animal Rebellion, a mass volunteer movement that uses methods of non- violent civil disobedience to end the animal agriculture.
Attendees marched to Parliament Square on August 17 for a rally, stopping on en-route to blockade Trafalgar Square for almost an hour.

"The purpose of the march is to unite the vegan community globally and to inspire vegans to speak up for animals in their everyday lives and get active in their local communities," Surge's website states.
"The Official Animal Rights March is community driven, with the mission of taking the animal rights movement directly to the streets in the thousands, united against the industries who exploit and use animals."
Last year, more than 28,000 attendees marching in 25 cities across the world 'demanding an end to all animal oppression'. London surpassed 10,000 protestors - a 400 percent increased compared to 2016.
