The letter written by Samuel Schulenburg, 19, a former pupil at the south London private school, contains 250 anonymous testimonies including 100 written by girls who went to neighbouring schools, such as James Allen’s Girls’ School (Jags), reported the Sunday Times.
The alleged accusations include assault, revenge porn, sexual violence, “slut shaming” and claims the school has an “established rape culture.”

In the letter, Mr Schulenburg, now at Oxford University, said: “The behaviour of…students is a testament to their entitlement, to their experience of an institution which has enabled their sexism, racism, their homophobia and their abusive tendencies.”
In a statement to the Sunday Times, Dr Joe Spence, master at Dulwich, “condemned unreservedly the alleged social and sexual misconduct” described in the letter.
He added the school plans to have lessons on issues such as consent, pornography and all forms of sexism
Jags said it “remains committed to supporting all students and staff in challenging unacceptable behaviour. Safeguarding our pupils is our priority and we take seriously and act upon any allegations within our community”.
There have been calls for an investigation by the Charity Commission into the private schools named to see whether they had breached charities law by failing to tackle sexism and uphold equal opportunities. Private schools are classed as charities.
It comes as a dossier from former and current pupils of private school, Westminster, emerged at the weekend containing allegations of sexual assault and abuse, reported The Times.
