How opposition politician Salum Barwany overcame discrimination and fear to become the first albino elected to office in Tanzania in 2010. Albinism is a genetic condition caused by a lack of the pigment Melanin, which affects the colour of the skin, hair and eyes. Though rare it is more common in parts of Africa, and particularly in Tanzania. There, albinos have long faced social stigma but in recent years many have been brutally murdered. The killings are carried out to harvest their body parts for witchdoctors who claim they can be used in magic potions to bestow wealth. Salum Barwany MP talks about growing up with albinism and his struggle to change attitudes. This episode is produced by Alex Last and Esther Namuhisa
