Top public school accused of 'toxic culture of racism' among pupils

Letter from Westminster alumni demands changes to teaching of black culture

More than 250 former pupils at Westminster School have signed a letter demanding that it combat the toxic culture of racism within the student body", promote the teaching of black culture and confront its links with the slave trade.

It is one of the first indications that Britain's public school system is now coming under pressure to follow the example of many universities and examine how it tackles racial and colonial issues.
