DMK workers on Monday burnt an effigy of Janata Party president Dr Subramanian Swamy in Udhagamandalam for raking up the 2G spectrum issue, leading to resignation of Union Telecom Minister A Raja, who represents Nilgiris parliamentary constituency.
Raising slogans against Swamy, they doused the effigy with petrol and set it ablaze, police said, adding that no arrests were made.
Swamy had filed a Special Leave Petition in the Supreme Court for a direction to Prime Minister Manmohan Singh to decide on his application, seeking prosecution of Raja.
Raja resigned last night.
DMK activists also staged demonstrations at Gudalur, Pandalur and Kothagiri against Swamy for allegedly making derogatory remarks against party president and chief minister M Karunanidhi, in an interview to a TV channel, police said.
Meanwhile, AIADMK workers burst crackers and distributed sweets to the public and partymen in Coimbatore, rejoicing over Raja's resignation.
