British band The Vamps star in a campaign video to launch The Diana Award's first National Stand Up To Bullying Day (July 5).

The campaign, which is also supported by Susanna Reid, Nicola Roberts and Eamonn Holmes, encourages people to post an image or video of themselves 'taking a stand, or raising a hand' as a sign of unity against bullying, using the hashtag #StandUpToBullying. James McVey from The Vamps commented 'It's crucial for us to recognise the importance of standing up to bullying - there is honestly no excuse for us to simply let bullying continue in the school and work place'.
