Girl Guides have launched a petition calling for education ministers to take action to end sexual harassment in schools.

The petition calls for a zero-tolerance approach, compulsory relationship and sex education and a duty on schools to prevent and tackle sexual harassment.

Hosted on change.org, it is addressed to Scotland's education secretary John Swinney, the UK Government's education secretary Justine Greening MP and Welsh education secretary Kirsty Williams.

The petition will be released by Girl Guiding's Advocate panel, a group of young women aged 14-25,at the launch event of the parliamentary Women and Equalities Committee report hosted at Girl Guiding HQ in London.

The committee's chair Maria Miller MP and equality campaigner Laura Bates will attend.

Research by the charity found that 59% of girls have experienced sexual harassment at school.

It found 75% said anxiety about experiencing sexual harassment affected their lives in some way including making them think twice about raising their hand in class.

Girl Guiding member Susie, 18, described her experiences of sexual harassment in school.

She said: "I was groped in corridors more times than I can remember. One corridor in particular was horrendous and everyone hated it - I had so many awful experiences there.

"I also remember one time in particular, when I was 11, walking past a group of guys and they suddenly blocked the way and grabbed me till I almost had to punch my way past them.

"After I got through I started crying and remember feeling awful - it just felt so horrible.

"A girl followed me to ask if I was OK - I was mortified that she'd seen what happened.

"It was weird, as a girl you were expected just to put up with it, to admit it upset you reflected badly on you and not the boys."

A Scottish Government spokeswoman said: "We want every child and young person in Scotland to develop mutually respectful, responsible and confident relationships with other children, young people and adults.

"We published updated guidance for teachers on relationships, sexual health and parenthood education in 2014. The guidance encourages equality and mutual respect from an early age and will support teachers deal with issues such as misogyny in schools.

"At the same time, our Mentors in Violence Prevention Scotland Programme is working hard to tackle gender stereotyping and attitudes that condone violence against women and girls."
