A host of stars including Dominic West, Gillian Anderson, Dame Joanna Lumley, Sophie Okonedo and Sir Mark Rylance are backing Survival International's global campaign for the Bushmen in the 50th anniversary year of Botswana's independence.

The campaign aims to secure the right of the Bushmen to return to their land in the Central Kalahari Game Reserve, established 55 years ago to protect the Bushmen's rights and ancestral home. Julian Lennon and Sir Sir Quentin Blake are also supporting the campaign.
