More than 100,000 English-speaking children in India’s information technology capital of Bangalore will soon have to switch to schools offering lessons exclusively in a Dravidian regional language, following a crackdown on more than 2,000 English-medium institutions in the state of Karnataka.

The state government’s promise on Monday to enforce a widely flouted 1994 language policy requiring compulsory Kannada-medium education in primary schools reflects resentment at the influx of relatively wealthy English-speaking IT workers into Bangalore.
