State Power Minister Srikant Sharma alleged that both Singh and Congress vice president Rahul Gandhi suffered from attention seeking disorder.
"Rahul Gandhi and his political guru, Digvijaya Singh, are suffering from attention seeking disorder and the party needs to get them medical help," Sharma told reporters during a programme on loan waiver scheme.
"Congress leaders are levelling charges against the BJP in the murder of Gauri Lankesh but they seem to have forgotten that it is their party which is at the helm in Karnataka," Sharma alleged.
BJP MP Ravindra Kushwaha termed Singh as anti-national and alleged that "leaders like him had destroyed the Congress".
Singh had stoked a major controversy by posting a tweet that used abusive language against the prime minister. He later disowned it, saying retweets were not endorsements, but the trolls did not spare him.
