As Britain prepares to celebrate the bicentenary of the abolition of slavery, an exhibition highlights its modern day version - human trafficking.
The exhibition, titled Slave Britain, will showcase pictures and testimonies of men, women and children who were brought into Britain.
The show by Panos Pictures is supported by Amnesty International, Anti-Slavery International, Eaves and Unicef.
The show opens on Wednesday at St Paul's Cathedral in central London.
Canon Ed Newell, director of St Paul's Institute, which is hosting the exhibition, said: "Just as churches played a key role in bringing an end to the slave trade 200 years ago, we hope this exhibition will also play a direct part in bringing to an end this demeaning and exploitative trade in human beings."
The exhibition will be open until 29 March.
