A group of people claiming to be Congress supporters staged a demonstration outside the RSS headquarters here tonight protesting against former Sangh chief K S Sudarshan's derogatory remarks against Sonia Gandhi.
The protest was held outside the RSS office located in central Delhi's Jhandewalan.
RSS leaders later filed a complaint with the police alleging that Congress workers had pelted stones at the office building. Police said they were investigating the matter.
While interacting with the media in Bhopal yesterday, Sudarshan had called Congress president Sonia Gandhi a CIA agent and accused her of plotting assassinations of her husband and former Prime Minister Rajiv Gandhi and his mother Indira Gandhi.
