Harold Macmillan was related either directly or by marriage to 35 of his 85 ministers. Only two members of his cabinet did not attend a fee-paying school. Fifty years on and what has changed in Britain? Very little, according to The Guardian's John Harris.
Then, of course, there is the Eton factor, which encompasses not just Cameron and Johnson, but plenty of their Tory colleagues, aides and advisers. Cameron's chief of staff is an Old Etonian, as is George Osborne's chief economics adviser. The Cabinet Office minister Oliver Letwin is too, along with the Tory chief whip, George Young, and the chief of the Downing Street policy unit – Jo Johnson, younger brother of Boris.
Despite the fact that around only 7% of British children are privately educated, 34% of MPs went to fee-paying schools, and the figure for Tory members of parliament is 54% (the Labour figure, to put that in perspective, is a mere 12%).
