Louis Theroux has announced that he'll be returning to the BBC Two this year and delivering a two-part documentary series. The first will focus on alcohol addiction, as Theroux will be sitting down with and speaking to the patients at King's College Hospital in London. The second is set to give insight into the millions of people living in the UK with long-term brain injuries. They're both expected to air later this year.

"BBC Two is delighted to welcome Louis Theroux back to the channel with a set of films covering British subjects with his usual penetrating documentary gaze and commitment to unpicking complex human dilemmas with highly sophisticated filmmaking," said Adam Barker, BBC Two Channel Editor.
