"Why Gandhi and Ambedkar didn't engage with Hedgewar, founder of RSS. Unfortunately, RSS/BJP has no option but to appropriate nationalist leaders like Sardar Patel, Gandhi and Ambedkar as they have no one to showcase as a nationalist leader," he tweeted.
Singh had also attacked the BJP on Saturday saying that some office-bearers of the party and Bajrang Dal were caught spying for the Pakistan intelligence agency Inter-Services Intelligence (ISI). "Some people, who were office bearers in Bajrang Dal and BJP were caught spying for the ISI. They have received bail but a case of treason should be pursued against them," he had said.
