Archbishop Desmond Tutu, pop stars Alesha Dixon and Pixie Lott and cricketer Andrew 'Freddie' Fintoff are among celebrities taking part in a 'virtual' march across the web today, in a bid to help stop cyberbullying.
Avatars of the celebrities, who are among three quarters of a million web users that signed up to take part in The Big March, which has been organised by BeatBullying.org, will make their way across 60 sites including MSN, MTV and AOL.
The march marks the start of Anti-Bullying Week, which takes place from November 15 to 19. BeatBullying is also calling for the government to introduce the Cyber Bullying Act, which would make it illegal to bully, abuse or harass Brits either online, via a mobile phone or using any other digital technology.

"Over three quarter of a million people are supporting our campaign, which must clearly demonstrate to the government the imperative need to act now to protect some of our most vulnerable children and young people," said Emma-Jane Cross, chief executive of Beatbullying.
