New Delhi, July 29: The Congress in Assam is in a dilemma over renominating self-styled lottery king Mani Kumar Subba for the second term from the Tezpur Lok Sabha constituency. Although the state Congress election committee does not foresee a problem in selecting the candidates for the forthcoming elections, in view of the decision to renominate all sitting MPs, the selection of the Tezpur candidate is expected to trigger a controversy. For the lottery king, problems may arise not from opposition within the state Congress but from the party's manifesto which proposes strict code of ethics in distribution of tickets to ensure that candidates with clean image are nominated. With CBI cases, indictment by the CAG in the Nagaland lottery scam and other criminal cases pending against him, state Congress leaders feel it would be difficult for Subba to meet the standards proposed to be set.
