DMK's Kanimozhi, CPI's D. Raja and four AIADMK candidates were Thursday declared elected to the Rajya Sabha from Tamil Nadu.
The four victorious AIADMK candidates are K.R. Arjunan, R. Lakshmanan, V. Maitreyan and T. Rathnavelu.
Maitreyan, Raja and Kanimozhi were re-contesting their seats.
DMDK's A.R. Elangovan lost the election, with just 22 votes as against the 34 needed to be elected. While the party has 29 legislators, seven had turned rebel and did not vote for the party nominee.
While Raja of the Communist Party of India was supported by the ruling AIAMDK and the Communist Party of India-Marxist, the DMK, which had 23 legislators, was supported by Congress (5 legislators), and the Manithaneya Makkal Katchi (MMK) and Puthiya Tamizhagam (PT) having two legislators each.
The poll saw 231 members of the 235-member assembly voting with PMK, having three legislators, boycotting the elections. One vote was declared as invalid.
