The Congress party has no moral authority to speak on democracy and freedom of speech after imposing Emergency in the country while being in power at the Centre 50 years ago, Union Minister of State for Mines and Minerals Satish Chandra Dubey said on Wednesday.

Addressing a press conference here at the BJP office, the Union Minister said the declaration of Emergency 50 years ago by the then Prime Minister, Indira Gandhi, would remain as the “darkest day” in the country.
