"Today is 27th June. The imposition of Emergency on 25th June, 1975, was the biggest and darkest chapter of direct attack on the Constitution. The entire country felt outraged. But the country emerged victorious over such unconstitutional forces as the traditions of the republic lie at the core of India," President Droupadi Murmu said in her opening address to a joint sitting of Parliament, amid cheers from the treasury benches and protests by the Opposition.
