Foreign imams who do not learn English should be banned from giving sermons in UK mosques, a Labour peer has said. Lord Ahmed’s comments come as a survey suggests imams lack professional and language skills to tackle the threat of radicalism among young British Muslims. Only 8% of imams preaching in British mosques were born in the UK, it found. Research at 300 mosques by Chester University for BBC News and the BBC Asian Network also indicated only 6% speak English as a first language. The report acknowledges the use of English is becoming more prevalent at Friday sermons but says more investigation is required to assess the frequency and quality.
