Bengal Chief Minister Mamata Banerjee called for the opposition to unite against the BJP today, pointing to the "threat" posed to democracy by what she called a "surveillance state" in the aftermath of the Pegasus scandal. The Chief Minister, who was addressing the people online on Martyr's Day -- a first since her landslide victory in the state elections -- said she would go to Delhi on July 27 or 28 and will be available for an opposition meeting if one is held. A number of opposition leaders heard her address in Delhi and other cities where it was played live on giant television screens.
