Prime Minister David Cameron says he will make universities disclose what proportion of poor and ethnic minority applicants they admit, in an attempt to end racial and class discrimination that "should shame our country and jolt us to action."

Writing in the Sunday Times newspaper, Cameron said that "if you're a young black man, you are more likely to be in a prison cell than studying at a top university."

He said universities like his own, Oxford, were "not doing enough to attract talent from across our country."

He also said the senior ranks of the military and large corporations were failing to include enough people from ethnic minorities or working-class backgrounds, as a result of "ingrained, institutional and insidious" discrimination.
