Winners of the One World Media Awards announced

Editor Bridget Harney, producer Leo Hornak and presenter Madeleine Morris celebrate Assignment's win last night

The BBC wins in three categories at the One World Media Awards in London last night.

Welcome to Lagos, a BBC Two observational documentary series, explored life in Lagos, Nigeria, one of the most extreme urban environments in the world. It picked up the documentary award.

Channel 4 presenter Jon Snow hosted the awards, now in their 23rd year, which recognise excellence in film, radio, print and new media that has the developing world as the focus.

With 13 categories, the winners are judged by figures from the media, government and international charities.

World Service's Assignment strand got the radio award for India's Microcredit Meltdown, an investigation into the crisis hitting India's microcredit industry.

The popular features award went to BBC Three's Blood, Sweat And Luxuries: Gold and E-Waste, in which six young British adults lived and worked alongside people in Africa who mine, manufacture, process and recycle luxury goods.

Channel 4 is the big winner

Lindsey Hilsum, international editor for Channel 4 News, picked up the award for journalist of the year. She was singled out for her reportage from Gaza, Afghanistan, Iraq and the Congo.

Channel 4 was the big winner on the night, taking a total of five awards from the 13 on offer. Two films for their international current affairs strand, Unreported World, took prizes for the television award and environment award.

A full list of winners is available on the One World Media website.
