Liz Truss's new Tory cabinet has the highest proportion of privately-educated ministers since Sir John Major's top team in 1992, new analysis shows.
The educational charity The Sutton Trust found that 68% of the Prime Minister's most senior ministers attended fee-paying schools - compared with 64% in Boris Johnson's first cabinet.
It is more than double Theresa May's first cabinet in 2016 - 30% attended independents - and more than David Cameron's 2010 coalition cabinet, with 62% the alumni of private schools.
The Sutton Trust estimates that the number of cabinet ministers who attended fee-paying schools is almost ten times higher than the general population - which stands at around 7%.
Ms Truss's cabinet has been hailed for its diversity, with none of the four great offices - Prime Minister, Chancellor, Home Secretary, and Foreign Secretary - held by white men for the first time.
But the new research highlights that just 19% were educated at comprehensive schools - Ms Truss included - while 10% attended a grammar school.
Two members of the cabinet, Chancellor Kwasi Kwarteng and Business Secretary Jacob Rees-Mogg, attended Eton College - a private school that has educated around 20 prime ministers.
Founder and chairman of the Sutton Trust Sir Peter Lampl said: "In Liz Truss's new cabinet, 68% went to private schools - almost 10 times the number in the general population."
"Truss continues the academic dynasty at No 10 that stretches back to the start of World War II: except for Gordon Brown, every Prime Minister since 1940 who went to university went to Oxford".
He added: " Liz Truss has pitched herself as the 'education prime minister', representing a potentially exciting opportunity to improve the school system and opportunities for children and young people across the country.
"Yet in terms of educational background, the make-up of her cabinet is less representative than that of her predecessor, with over two-thirds from independent schools.
"Today's findings underline how unevenly spread opportunities to enter the most prestigious positions continue to be. Making the most of talent, regardless of their background, must be a priority".
Earlier on Wednesday, Therese Coffey, the newly appointed deputy prime minister and close ally of Ms Truss insisted the new cabinet was a "government of all the talents that we have in this party".
"Liz has appointed a cabinet of a mixture of whether it's people of her proactive supporters, people who did not support her as well," she said.
Ahead of junior ministerial appointments being unveiled on Wednesday, Ms Coffey said that "people will be able to see that we will continue to focus on having a broad church of people in our government".
