In Karnataka, the latest flashpoint between the ruling BJP and the opposition Congress is playing out around an unusual prop - the underwear or "chaddi". It all started when members of the Congress students' wing NSUI (National Students Union of India) burnt underwear outside the Home of Education Minister BC Nagesh last week, calling it their protest against "saffronisation" of school textbooks. The workers were seen setting fire to a pair of khaki knickers - the kind associated with the BJP's ideological mentor Rashtriya Swayamsevak Sangh (RSS).
