He also criticised Delhi Chief Minister Arvind Kejriwal, saying he crossed all limits by alleging that the Prime Minister was conspiring to kill him.
"Aam Aadmi Party has become a one-man party. It does nothing except bad-mouthing the Prime Minister," Bhushan alleged while addressing the concluding session of a two-day Swaraj Abhiyan national convention here.
"He (Kejriwal) has not kept a single department with himself. What is he drawing a salary for? He crossed all limits when he said Modi is conspiring to kill him," Bhushan said.
