Condemning Ashutosh, the AAP election in-charge of Gujarat, over his controversial blog, the BJP said it "won't tolerate insult to Mahatma Gandhi."
Earlier, angry activists set the AAP spokesperson's effigies on fire at Ahmedabad, Rajkot, Junagad and other cities.
In the blog written for a TV channel, Ashutosh had referred to the alleged affairs of icons like Jawaharlal Nehru and Gandhi while seeking to defend Kumar who was sacked as minister after a CD purportedly showing him with a woman in a "compromising position" surfaced.
He said actions' of AAP ministers and MLAs shows the Arvind Kejriwal-led party has reached the "nadir of political values."
"AAP spokesperson Ashutosh has tried to malign Mahatma Gandhi by making cheap comments against him, all in order to save the image of his minister who was found indulging in a dirty act," Jadeja said, adding that AAP members had also made "dirty comments" on Jain monk Tarun Sagarji.
