Chennai, May 14 (IANS): DMK President M.K. Stalin on Tuesday challenged Prime Minister Narendra Modi and BJP's Tamil Nadu President Tamilisai Soundararajan to quit politics, if they cannot prove that he was in talks with their party for a post-poll alliance.

Soundararajan had claimed that Stalin was in talks with Modi for post-poll alliance.

Rebuffing her claim, the DMK chief said he would quit politics if Soundararajan can prove that he was in talks with the Bharatiya Janata Party for a post-poll alliance and asked whether she and Modi would quit politics if they can't prove their claim.

The BJP, which is on the brink of electoral defeat, is a master in creating confusion in the minds of people, he said, alleging that Soundararjan made such a comment in order to prevent the minorities from voting for DMK in the May 19 by-elections for four Assembly constituencies.

Stalin also said it was he who first proposed Congress President Rahul Gandhi as a Prime Ministerial candidate and termed Modi as a "fascist, sadist and a dictator".
