Sutton Trust founder Sir Peter Lampl, who went to the same school as the Prime Minister, Reigate Grammar, made the claim as he attacked the Government’s plans to charge VAT on private school fees.
A Government spokesman said: “Ending the VAT break for private schools means an additional £1.7 billion a year that can be invested in our state schools, where 94% of this country’s children are educated.
Sir Peter also claimed the “regressive” decision to charge the tax on school fees would deprive children of extra-curricular activities, “vandalising” the private sector.
The school was funded by the local council when the Prime Minister joined, but became a private school two years into his time there.
Introducing VAT on private school fees is aimed at raising more money to fund state schools.
