Cardinal Vincent Nichols has signed a letter calling on people in Britain to “challenge racial and communal prejudice wherever it is found”, following an apparent surge in ethnic tensions last week.

The cardinal, along with the Archbishop of Canterbury Justin Welby, Chief Rabbi Ephraim Mirvis and Muslim leader Ali Razi Rizvi, said in a joint letter that “increasing reports of inter communal discord and racial hatred are cause for the gravest concern”. Since the referendum result reports of racial hate crimes have risen by 57 per cent.
