Paying tributes to Bharatiya Jana Sangh founder Syama Prasad Mookerjee on his birth anniversary, Union Minister Amit Shah said J&K wouldn't have become an integral part of India without him. "He sacrificed himself for Kashmir...raising the slogan 'Ek desh mein do Vidhan, do Pradhan aur do Nishan nahi chalenge'," Shah added. Jana Sangh is the ideological parent organisation of BJP.
