Is the craze for English in India a mixed blessing? asks Mark Tully, the BBC's former long-time India correspondent in this BBC article, which is an edited extract from his new book Non Stop India. He goes on to say that it is the knowledge and use of English that is propelling India to economic superpower status. However, the other side to this coin is that English may kill off other languages spoken in India, of which there are hundreds. Tully notes that history teaches us that the threat to Indian languages has the potential to provoke a violent backlash.
