Sometimes you hear a piece of news which knocks you for six. During the last election campaign I had some fantastic help from some teenagers from the village of Worsted in North Norfolk, one of them being a young lady called Charlotte Robinson.

Charlotte emailed me out of the blue in the spring and asked if she could come and do work experience at 18 Doughty Street for a week this summer. We emailed back and forth and I suggested she come last week. But I never heard back from her. I now know why. I've just been told that she died last week from an eating disorder. She can't have been more than 18. What a terrible waste of a life. Her wonderful family will be devastated. RIP Charlotte.
