CPI National Secretary D Raja today filed his nomination papers for the June 27 biennial elections to six Rajya Sabha seats from Tamil Nadu.
Principal opposition party DMDK also entered the fray as party treasurer A R Elangovan filed his nominations, taking the total number of nominations filed so far to eight.
The five candidates from AIADMK and Kanimozhi from DMK have already filed their nominations.
In the backdrop of the ruling AIADMK deciding to support CPI's D Raja, Chief Minister Jayalalithaa today announced withdrawal of her party's fifth candidate K Thangamuthu from the contest.
Though DMDK has 29 seats in the 234-member Tamil Nadu Assembly, seven have turned rebels and expressed their loyalty to Jayalalithaa, saying they want to ensure development of their constituencies.
