Congress workers on Saturday continued their protest against the disqualification of party leader Rahul Gandhi as a Lok Sabha member by covering their mouths with black bands and tying locks on them. Mocking the protest, Chief Minister Shivraj Singh Chouhan said Rahul Gandhi should have put a lock on his mouth when he made the statement which led to his conviction for defamation. State Congress leader Bhupendra Gupta said the Bharatiya Janata Party (BJP) under Prime Minister Narendra Modi wanted to lock the opposition up to throttle democracy in India.
