With multiple arrests, fireworks being launched into crowds outside Buckingham Palace, and thousands of angry protesters wearing masks and balaclavas, London's second Million Mask March appeared to onlookers as little more than an excuse for a mass brawl.

But on the inside, among the masses of riot police, protesters and confused tourists caught up in its wake, the event, organised by Anonymous to protest against government oppression, was a mostly peaceful evening.

IBTimes UK attended the march, which ran from Trafalgar Square to Parliament Square, before heading to Buckingham Palace, Green Park and eventually Regent Street - and two main points stood out; firstly, the diverse mix of people taking part, but also the mixed messages they were trying to get across.
