David Bowie has been honoured with a posthumous award for his final album Blackstar at an awards ceremony at London's Savoy Hotel while Lord Andrew Lloyd Webber received the Outstanding Achievement award.

Bowie's 25th studio album won the Pop Music category at The South Bank Sky Arts Awards, with Iggy Pop accepting the gong on his late friend's behalf, with a touching video message recorded from his US home.

Phoebe Waller-Bridge, tipped to take over from Peter Capaldi in Doctor Who, won the comedy category for Fleabag.

Harry Potter And The Cursed Child scooped the theatre gong, which was presented by Bond director Sam Mendes.

Happy Valley, starring Sarah Lancashire, beat off competition from The Crown to win best TV drama.

Sir Cameron Mackintosh called his former collaborator Lloyd Webber "the biggest catalyst in the musical world in my lifetime", and paid tribute to his ability to make "a great piece of theatre" out of the "most unlikely subject".

Pop paid tribute to Bowie, saying that the late star changed "the game in rock and roll and in popular music" but was also a fan of The South Bank Show.
