Congress president Mallikarjun Kharge has said that the RSS should be banned, claiming that most law and order problems in the country arise because of the BJP and the RSS. He pointed out that even Sardar Vallabhbhai Patel had once imposed a similar ban. The BJP has strongly criticised his remarks, accusing the Congress of having ignored Patel and his contributions for decades. So, what is the controversy about, and what led the Congress president to make such strong comments against an organisation that supports the ruling party?
