Thousands of protesters will gather in cities around the world, in protest against issues such as austerity. If you’re taking part we’d like to hear from you

Thousands of people are expected to take part in protests – known as the Million Mask March – around the world on Saturday, to demonstrate against austerity economics, official corruption, erosion of civil liberties, surveillance and a litany of other causes.

This year, the demonstration is likely to be one of the biggest yet – over 20,000 people have indicated they will attend on the main Facebook event page.

Last year, police and protestors clashed in London, and a police car parked close to the Houses or Parliament was set on fire. This year, Scotland Yard has imposed restrictions on protesters and have stated that activities must take place between 6pm and 9pm. Any person in breach of these conditions may face arrest, police said.
