The Charity Commission will be monitoring Eton College after allegations that some of its pupils jeered at and insulted girls visiting from another school.
The commission confirmed that it would contact Eton’s trustees after the school filed a serious incident report with the regulator.
According to the BBC, girls from a nearby state school were subjected to “misogynistic language and racial slurs” when they visited Eton last week.
Eton is a charity as well as being one of the most prestigious and expensive all-boys public schools in the country, with annual boarding fees set at about £40,000.
The charity told Third Sector that it had apologised to the people affected and confirmed that some pupils had been “sanctioned” over their behaviour.
The alleged abuse came shortly after a speech by former UK Independence Party leader Nigel Farage, who had been invited to address an event at the school.
A Charity Commission spokesperson said: “We can confirm that in line with our guidance, Eton College filed a serious incident report relating to a recent event.
“We will be engaging with the charity around this matter and will monitor their handling.”
A spokesperson for Eton said: “The behaviour of some Eton pupils at a recent talk by Nigel Farage was totally unacceptable and Eton has apologised unreservedly to those affected.
“Eton demands that all our pupils treat others with decency and respect. That did not happen on this occasion and the school has investigated and sanctioned a number of pupils. The head master has addressed all boys to reinforce the school’s expectations.”
