KATE Middleton was so badly bullied at an elite boarding school that her parents were forced to move her to another school after just two terms.
A gang of girls reduced the 13-year-old Miss Middleton, who is set to marry Prince William at the end of the month, to tears on numerous occasions and bullied her by putting faeces in her bed at the prestigious Downe House, a new biography is set to reveal.
The book, entitled Kate Middleton and written by celebrity biographer Sean Smith, is due to be published shortly after the Royal Wedding on 29 April.
It says that Miss Middleton's unhappiness at the near-29,000 a year boarding school in Thatcham, just a few miles away from her family home in Bucklebury, prompted her move to the famous Marlborough College in Wiltshire halfway through the school year. Mr Smith, who has written bestselling biographies of Robbie Williams, Kylie Minogue and JK Rowling, discovered the truth about Miss Middleton's move from Downe House after interviewing her old school friends.

One friend from Marlborough, Jessica Hay, said of Miss Middleton's time at Downe House: "She hated it, absolutely hated it. The girls were horrible. They used to put faeces in her bed and she was very, very badly bullied.
"She was picked on because she was perfect - well turned out and a lovely person. She was not the type of person to stick up for herself.
"They saw something they could pick on - and gangs of girls can be very nasty."
The Middleton family have always said that their daughter just didn't "fit in" at the school, which counts TV presenter Clare Balding, comedienne Miranda Hart and model Sophie Dahl among its former pupils.
Miss Middleton continued at Marlborough College until her sixth form, achieving two A grades and a B at A-level before studying Art History at St Andrews University, where she met Prince William.
