Addressing a gathering after the march, Youth Congress national president Amrinder Singh Raja Brar said,"We demand immediate resignation of MP Chief Minister over the deaths in connection with the scam."
The march started from Youth Congress' office and culminated at Jantar Mantar.
Brar said that an independent and impartial probe into the Vyapam scandal is not possible till the Chief Minister remains in chair as the investigating agencies are functioning under state government.
Amid mounting outrage over the Vyapam deaths, Opposition today sharpened its attack on Chouhan, demanding his sacking over "cold-blooded murders" but BJP backed its beleaguered leader and disfavoured CBI probe.
