Sikkim Chief Minister and SKM supremo Prem Singh Tamang, former CM and SDF chief Pawan Kumar Chamling are among the 146 candidates in fray for 32 assembly seats which will go to the polls on Friday amid elaborate security arrangements in the Himalayan state. Tamang, who is spearheading the ruling Sikkim Krantikari Morcha (SKM)'s bid to retain power, is contesting from two assembly seats, Rhenock in Gangtok district and Soreng-Chakung in his native Soreng district. The SKM chief who is seeking a seventh consecutive term as MLA, is locked in a multi-cornered contest in both assembly constituencies with former minister and SDF nominee Som Nath Poudyal being his main challenger in Rhenock assembly constituency, while SDF candidate AD Subba is his main opponent in Soreng-Chakung assembly constituency. The SKM supremo's wife Krishna Kumari is contesting from Namchi-Singhithang assembly constituency where she is locked in a quadrangular contest in which the SDF has put up Bimal Rai. Sikki
