The start of Anti-Bullying Week received a Hollywood boost as actor Will Poulter helped to get the campaign under way.

Poulter, who played Kenny in summer smash hit We’re the Millers, was joined by musicians Jordan O’Keefe and Tich, and TV presenter Carrie Grant, at an event in the International Hotel, Canary Wharf, which was designed to get young people exploring bullying through drama, song and poetry.

A debate was chaired by ITV news presenter Charlene White, while Waterloo Road TV star Rebecca Craven and Layton Williams, from BBC Three comedy Bad Education, ran drama workshops with anti-bullying ambassadors from The Diana Award charity.

Bearing the name of Diana, the late Princess of Wales, the charity has trained more than 5,000 ambassadors in 600 schools across England.

Tessy Ojo, the charity’s chief executive, said: “The programme is designed to empower young people by providing the tools and confidence to campaign against bullying.

“Bullying no matter how it happens, is always wrong.”
