Actor Nicholas Hoult supported this month's Christian Aid Week by visiting a project in Kenya's Nairobi slums that provides clean water and sanitation for thousands of people.

"When you first see the sewage and the cramped living conditions and experience the smell, it's stifling," he said. "The only comparison I can make with home life is that it's like a music festival where you can't get out, the toilets never get cleaned and there's no music. That really doesn't do justice to it. All those I met there were in a vulnerable situation but showing great strength."
