A 15-year-old girl has died from a drugs overdose nearly two years after her mother was found hanged at their home.

Whitney Berridge was taken ill in Basingstoke, on April 19 and was later that day declared dead.

Toxicology tests have revealed that the teenager died as a result of a drugs overdose and an inquest will be held into her death on July 2.

Whitney's mother, Shanie, was found hanged at the then family home in the Popley area of Basingstoke on May 6, 2012.

Leigh-Ann O-Leary, Whitney's aunt who she lived with, said that her mother's death had affected the schoolgirl deeply.

She said: ''Whitney and her mum were very close. When Shanie died, Whitney died with her.

''Something absolutely changed her when her mum died.''

She added that she had been trying to arrange counselling for Whitney, who suffered from Wolff-Parkinson-White syndrome - a heart condition that can cause the heart to beat abnormally.

Whitney had been studying for her GCSE exams at the Everest Community Academy. Julie Rose, principal, said: ''She was a year 11 child who should this week be taking exams and isn't quite sadly.

''She was a lively, interesting young lady who had her life ahead of her and unfortunately has been taken away and it has hit our students very hard and we are having to work quite hard to support them.''

Hundreds of friends gathered in Basingstoke's War Memorial Park on April 28 to remember Whitney on what would have been her 16th birthday. They released pink balloons, her favourite colour, and lit candles in her memory.
