Research by Stonewall shows that more than half (55 per cent) of gay young people experience homophobic bullying.
The Lesbian Gay and Bisexual charity says that if homophobic bullying goes unchallenged, it can have severe negative consequences for young people.
It says three out of five gay young people say homophobic bullying affects their school work and many have skipped school because of it. Homophobic bullying also impacts on young people's self-esteem and ambitions.
