A pupil at a top High Wycombe school has reportedly died in a horrific quad bike accident. 

Iris Annabel Goldsmith - the 15-year-old daughter of millionaire financier Ben Goldsmith - crashed in a field next to the family farm in North Brewham, Somerset, on Monday, according to national reports. 

She was a pupil at independent girls' boarding school Wycombe Abbey and had been studying for her GCSEs. 

She is believed to have just started her summer break when the tragic accident happened. 

Iris was an heir to both the Goldsmith and Rothschild dynasties. 

A family friend told the Mail: ‘This is the most awful accident. Iris was a complete firecracker – an absolute delight. Everyone in the family loved her to bits.

"She was beautiful, charming, intelligent, wonderful company and absolutely the loveliest person you could meet. ‘Ben and Kate are completely devastated.

"They are numbed to their core and united in their grief."
