An electronic pop trio fronted by Skins actor Olly Alexander have been tipped as the ones to watch this year by industry insiders.

The band, Years & Years, topped the BBC Music Sound of 2015 list.

They said: "We can't really get our heads round it, Olly nearly passed out when we found out, it was so surreal and emotional. It feels like it means we've got a real shot, which means the world to us. People are going to listen to what we're going to do, and we've just got to not muck it up. We've got to make the most of it and deliver."

Alexander, who played Jakob in Skins, has also starred in films including The Riot Club.

The BBC list was compiled after around 140 music industry experts including DJs and critics were asked to name their three favourite new acts.

Previous winners have gone on to huge worldwide success and include Sam Smith, Jessie J, Adele and Ellie Goulding.

George Ergatoudis, head of music for BBC Radio 1 and 1Xtra, said: "Lead singer Olly Alexander is blessed with a distinctive, intoxicating voice that works beautifully with the band's emotive electropop production. They fully deserve to top BBC Music's Sound of 2015 and they're surely set for stellar success."
