The Bharatiya Janata Party national president J P Nadda on Thursday alleged all parties come to power to serve their families and earn through commission except the BJP. “All political work for their families and earn through commission except the BJP. Right from Prime Minister Narendra Modi to Karnataka Chief Minister Basavaraj Bommai, everyone in BJP toils day and night to serve the people and to change their image and destiny,” Nadda was addressing people after inaugurating BJP offices in 10 districts of poll-bound Karnataka.
