Anti-corruption crusader Anna Hazare today lauded the Centre for its “bold and revolutionary” decision of demonetising Rs 500 and Rs 1,000 currency notes, saying it will curb black money. “This revolutionary step will curb black money, corruption and terrorism (funding) to a large extent,” Hazare told. “The previous governments never showed the will to crackdown on black money. The present dispensation has taken a bold step and this will strengthen the democracy,” he said.
