On a night of few surprises, Adele and Ed Sheeran took home two Brit Awards apiece as Ethan Johns scooped the prize for British Producer.
Johns, who recently produced Laura Marling's second album A Creature I Don't Know, saw off competition from Paul Epworth, who worked on Adele's all-conquering 21 album, and Flood, who collaborated with PJ Harvey on Let England Shake.
There was little controversy during the ceremony itself, though television producers were forced to apologise for cutting off Adele's acceptance speech as she won the award for British Album of the Year.
Performances came from Coldplay, Ed Sheeran, Noel Gallagher, Olly Murs, Florence And The Machine, Rihanna, Bruno Mars and Outstanding Contribution to Music award winners Blur.
