Several Opposition parties, including the Congress, will take out a 'Tricolour March' from Parliament House to Vijay Chowk on Thursday, alleging that "democracy is under attack" by the BJP.

MPs of like-minded Opposition parties such as the DMK, the Samajwadi Party, the RJD and the NCP, and from the Left, besides the Congress, will begin their march at 11.30 am.
