London 'Anonymous' activists hold Million Mask March in lockdown

Londoners defied the latest lockdown imposed by the government and took to the streets for the annual 'Million Mask March' - linked to activist group Anonymous. Protesters - many waving Anonymous flags and smiling Guy Fawkes masks, made popular by the anti-establishment hackers and the film "V for Vendetta" - demonstrate against austerity, mass surveillance and oppression.
