A staggering quarter of girls aged between 10 and 18 have been the subject of some form of cyber-bullying according to a poll from Girlguiding UK.
A survey of more than a thousand girls revealed that 28 per cent had been bullied by internet or email, with girl-on-girl bullying on the rise.
"As the UK's largest organisation providing a safe female-only space for girls and young women, we see it as our responsibility to give girls and young women the knowledge and self-confidence to deal with issues that worry them," said Girlguiding UK chief executive Denise King.

"With girl-on-girl bullying on the increase and bullies using new methods to single-out individuals we know this is a serious issue for thousands of girls and young women," she added
"However, we also want to emphasise to girls the skills involved in being a good friend and these are important not just when you are young but throughout your life."
