In pictures: Slave Britain

Orphaned at 15, Sheila was taken from Uganda by a family friend and sold to a man in the UK for sex. She escaped but, not knowing where or to whom to turn, was forced to sell her body to survive.

Pregnant and desperate, she eventually contacted the Refugee Council.

"They have helped me so much. I had no friends or family. Now I feel like I have a family.

"My daughter is four now and I am pregnant again. Before, I used to feel like a monster; now I am a human."
