Congress President-elect Rahul Gandhi on Tuesday said he would not tolerate any kind of nasty language, referring to Mani Shankar Aiyar's "neech" remark against the Prime Minister, but added that whatever Narendra Modi had said about former Prime Minister Manmohan Singh was "also not acceptable".Gandhi made it clear that no nasty or filthy language will be tolerated against the Prime Minister"I have cleared my position through my words and also through action. The way Mani Shankar Aiyar attacked Prime Minister, I am not going to tolerate such comments against the post of Prime Minister. And you all saw the action," Gandhi said.Slamming Modi for his barbs against his predecessor, the Congress leader said, "What the Prime Minister said about Manmohan Singhji is also not acceptable. He was Prime Minister of the country and has done a lot for it." He also said that as Congress President his priorities will be to change the nature of the politics. "Politics should not be ugly and nasty. There is a lot of anger in politics these days, but politics should be carried with love," he said. Asked about Modi attacking him in public rallies, Gandhi said that he will not use any such words for the Prime Minister."Modiji always keeps on screaming against political opponents. He even used a lot of words for me. But I am not going to use any filthy language against him because he is the Prime Minister," he said.
