In another depressingly pointless round of industry backslapping, electronic artist James Blake has won this year's Barclaycard Mercury Prize with his second album, Overgrown.

The Mercury Prize, for the best British or Irish album of the year, was handed out at the Roundhouse in north London.

Speaking backstage, the 25-year-old said he felt "jubilant and confused" adding that "This is the first award I've ever won apart from a tennis trophy I won when I was 12."

He beat bookies' favourite Laura Mvula and stars like David Bowie and Arctic Monkeys to the £20,000 prize.

The singer-songwriter had previously been nominated for the Mercury Prize in 2011 for his self-titled debut album.
