A 90-year-old tradition is about to become history. The Rashtriya Swayamsevak Sangh -- the ideological mentor of the BJP which got its pracharak into the Prime Minister's Office in 2014 - announced that it is shedding its old image. The khaki shorts which have symbolised the Sangh for 9 decades, will be soon replaced by trousers. The khaki colour, however, will stay.
