Shadow education secretary Tristram Hunt pledged to clamp down on homophobia in schools yesterday as campaigners warned that politicians must “put money where their mouth is.”

Kicking off LGBT history month celebrations, Mr Hunt said he wanted a zero-tolerance attitude towards the “deeply troubling” bullying.

“The use of homophobic language and other forms of homophobic bullying is damaging the life chances of so many young people,” he said.
