According to the most recent census, English is not the main language of 4.2 million people in England and Wales (7.7 per cent of the population); 726,000 people cannot speak it well and 138,000 speak no English at all. Many of us non-native speakers will at some point have to deal with the justice system, in one capacity or another (my first exposure was as a juror). The right to be tried in a language you understand is guaranteed under Article 6 of the European Convention on Human Rights (ECHR).
