He was honoured with a Music Industry Trusts Award and was presented with the award by past winner Elton John, while Prince Charles paid tribute to Gary in a video message from his jubilee tour of Australasia.
Gary, 41, was joined by Take That bandmates and wife Dawn at the bash, with fellow X Factor judges Louis Walsh, Nicole Scherzinger and Tulisa also in attendance.
‘I’ve been doing this for 22 years now,’ said Gary. ‘And the one thing that’s more apparent to me that ever before is how much I love performing.
‘I feel really lucky to be able to do it. It’s so special when you get something like this, because it’s recognised within the industry. I’m a lover of this industry and would do anything to protect it.’
