Julian Assange, founder of WikiLeaks, will be giving a Christmas speech to supporters at the Ecuadorian Embassy in London on December 20, 2012.
Organizers are hoping for as many supporters as possible to help get a huge crowd of people to show Julian and WikiLeaks that they stand in solidarity.
The event starts at 6:30 pm (GMT) with songs of solidarity lead by the South London Massive, singing their hit "I shall be released!", along with VFPUK, Lovers Electric and the Vigiliers All.
Assange will start the speech to mark the 6 months of his imprisonment at the Ecuadorian embassy at 7:00 pm local time (GMT).
Supporters should bring candles and food.
