ONE of Britain's best young sailors who competed in waters off Weymouth and Portland killed herself without any sign or warning, an inquest heard.

Jess Eales, 17, was found hanged in the New Forest the day after her 17th birthday.

Now her family want an anti-acne drug she was using, Dianette, investigated as it is known to cause depression as a side effect.

The inquest heard friends noticed she had become quiet during her birthday meal after not hearing from a boy she met in Portugal while competing for Great Britain days before her death.

In a statement read out to the inquest, father Nicholas said the family knew of her relationship and were not concerned and they were more worried about side effects of Dianette.

Mr Eales added: "The family has asked this drug be yellow-flagged as a result."

But Central Hampshire coroner Grahame Short ruled out the drug's involvement in her death as she had been taking it for six months without showing any signs of depression.

A European Medicines Agency review in 2013 also ruled the benefits of the drug outweigh the risks.

Recording a verdict of suicide, Mr Short said: "I can understand that her parents have been wracking their brains to try to understand why she did this but we should not underestimate the pressures on teenagers these days, particularly high achievers like Jess.

"The sad part is she felt unable to share these concerns with friends and family before she reached this decision. It is a tragedy for all concerned."
