Protesters from around the world are descending on London in preparation for Thursday's much-anticipated G-20 Summit. British police are preparing for tens of thousands of demonstrators to protest at four main sites across London.
Are you planning on protesting, or watching them? Send us your photographs. The best photos will be published on the Huffington Post.
The slideshow below contains photographs submitted by HuffPost readers who attended Saturday's event. If you will be attending any G-20 rallies during the rest of this week, send your pictures to firstname.lastname@example.org.
