GORDONSTOUN School has fought back against claims Prince Charles hated his time there, producing old speeches in which he praises the institution.

Prince Charles infamously described the Moray boarding school as “Colditz in kilts” and new Netflix drama The Crown recently showed the young Royal being bullied.

Now the £36,909 school has decided to strike back by digging out a speech and an interview given by the Prince in the 1970s.

In a speech to the House of Lords, in 1975, Prince Charles said: “I am always astonished by the amount of rot talked about Gordonstoun and the careless use of ancient cliches used to describe it.

“It was only tough in the sense that it demanded more of you as an individual than most other schools did, mentally or physically.

“I am lucky in that I believe it taught me a great deal about myself and my own abilities and disabilities.

“It taught me to accept challenges and take the initiative – why else do you think I am brave enough to stand up before your Lordships now?”

And in a magazine interview in 1974, Prince Charles said: “I am glad I went to Gordonstoun. It wasn’t the toughness of the place –- that’s all much exaggerated. It was the general character of the education there.”

A school spokeswoman provided the speech and article as “useful background information and illustrate what the Prince of Wales has already said about Gordonstoun in the past”. However, she said they “do not comment on individual alumni experiences”.
