Don McCullin: Life Interrupted

Don McCullin's new exhibition focuses on the victims of Africa's devastating HIV/Aids pandemic.

In South Africa, antiretroviral treatment is free, but in Zambia the cost of the drugs (£6 per month) is beyond the means of most HIV-positive people.

In liaison with Christian Aid, McCullin has visited both countries, retracing the steps of a trip first made back in 2000.

In South Africa, previous subjects are doing well, but in Zambia he found himself photographing orphans.

Intensely personal, these humane, thoughtful images contrast hope with despair.
