Robbie wins Brits best song prize
Robbie Williams has now win 15 Brit Awards
Robbie Williams' track Angels has won the prize for the best British song of the past 25 years at the Brit Awards.
Williams performed the track as a duet with Joss Stone at the event, hosted by Chris Evans.
Teenage singer Stone walked away with the awards for best female artist and best urban act.
US act Scissor Sisters led the winners so far with three prizes, while Franz Ferdinand and Keane went home with two awards each.
The US band - who opened the show with Take Your Mama - won the best international act and newcomer awards, as well as best international album.
Franz Ferdinand, who were shortlisted in five categories, won best rock act and best British group, an award they dedicated to late DJ John Peel.
But they missed out on best British live act, which went to Muse. Keane won best British album and breakthrough act. Will Young won the best single prize for Your Game.
McFly won the best pop act prize, and Gwen Stefani picked up the best international female artist award. Eminem won the male prize.
Best British male artist winner Mike Skinner - aka The Streets - does not usually attend award ceremonies, but the Birmingham hip-hop artist performed his hit Dry Your Eyes at the ceremony.
However, he did not collect his prize. A bandmate informed the crowd Skinner was "in the toilet".
After beating Amy Winehouse, Jamelia, Natasha Bedingfield and PJ Harvey to the best British female prize, Joss Stone said: "I don't know what to say. I don't like doing this at all. I'd like to thank my family for being really supportive and everybody that made my record with me."
"I don't even know what to do right now. Thank you all you guys for voting for me, I feel sick right now."
Viewers of digital music TV channel MTV Base voted Stone the winner in the best urban act category.
Little Britain comedy duo Matt Lucas and David Walliams presented the best song prize to Robbie Williams dressed as his former Take That colleagues Gary Barlow and Howard Donald, leading him to quip he was "always the talented man of the band".
Scissor Sisters won three awards at the ceremony
Williams' track beat songs by Will Young, Queen, Kate Bush and Joy Division in a vote by BBC Radio 2 listeners.
It is his 15th Brit award, having already received 10 solo awards and four with Take That. He told the audience: "I'm just amazed that my career keeps going."
Collecting the best rock act prize, Franz Ferdinand singer Alex Kapranos said: "We've had a smashing time and we think it's time for someone else to have a go."
The Scottish four-piece - who played Take Me Out - face stiff competition in the best British group category from Muse, Snow Patrol, Keane and Kasabian.
Keane frontman Tom Chaplin thanked fans for enduring "rubbish gigs" after they won the British breakthrough act prize.

He added: "A lot of people don't think it's cool that we've had the guts to be ourselves but it's a vital part of who we are as a band and receiving this is recognition of that."
Scissor Sisters singer Jake Shears thanked his record label "for taking a gamble on us" and the British people "for embracing us and giving us the best year of our lives".
Frontwoman Ana Matronic added: "I have Cornish, Welsh and Irish heritage and it's amazing to be embraced by a place that I owe my ginger hair to."
