Prince William had a very telling nickname when he was younger because he used to be very “unruly” and even disrupted a children’s party by throwing sandwiches around once.

The Prince of Wales was known for being very “cheeky” and “noisy” at home and school that even his mother, the late Diana called him “a holy terror” once.

Royal biographer Robert Lacey wrote in his book Battle of Brothers that such were the young prince’s exploits as a child that he was known as Basher Wills or Billy the Basher.

He claimed that William often got “involved in playground fights” with other children.

The writer wrote: “The young prince had picked up his nicknames of ‘Basher Wills’ or ‘Billy the Basher’ when he joined Mrs Jane Mynors’ Nursery School in Notting Hill, not far from Kensington Palace, in September 1985.

“Noisy, cheeky and defiant of discipline, Wills soon angered his classmates by pushing his way to the front of the dinner queue and getting involved in playground fights. The Prince’s mother, Princess Diana, once even called her son ‘a holy terror’.”
