A Wimbledon school girl’s letter to David Cameron on cyber bulling is amongst 13 teenage winners in Anne Frank inspired national letter-writing competition.

The Anne Frank foundation’s, ‘Thirteen in 13 campaign’ invited 13-year-olds across Britain to write short letters to the Prime Minister on things they would like to see changed.

Ciara Wall from Wimbledon wrote to the PM urging him to pass legislation to curb cyber bulling. Issues raised in other winning letters included poverty, racism, euthanasia and teenage health problems.

Ciara wrote: "It is unbearable to think of a child as young as eight receiving threats and bullying messages over the internet and feeling unable to tell their parents for fear of the bully and shame.

"I urge the government to pass laws to protect these young people from ever experiencing the feeling of worthlessness and humiliation at the hands of a bully."

On Friday July 26 Mr Cameron published a reply to all the winners in The Times.

He said: "Seventy years ago Anne Frank wrote in her diary, ‘I must uphold my ideals, for perhaps the time will come when I shall be able to carry them out’. Tragically that time never came for her - but it will for you. And on the strength of these letters, I can say with confidence that the future of our nation is very bright indeed."

A panel of judges, which included leading authors for teenagers and Anne Frank’s step sister Eva Schloss MBE, chose the thirteen winning entries to be presented to the Prime Minister from over 1,300 submitted.
