Around 200 anti-capitalist protestors, many affiliated to the Occupy movement, gathered outside parliament late Monday in a demonstration against government cuts.
There was brief unrest when police moved in to move the demonstrators -- many of whom were wearing Guy Fawkes masks -- back from the main parliament gates and onto the grass at Parliament Square.
Demonstrator Cian, 19, said: "I just want to be part of a protest against the government, against the cuts when they are spending billions of pounds on war.
Student Kree Love, 18, explained: "People have come to this protest because it is central and it is the best way to get our point across."
Police can forcibly remove any protesters that set up camp in Parliament Square under legislation passed last year.
