The DMK on Monday named two party nominees for the Rajya Sabha election, effectively quashing speculations of former Prime Minister Manmohan Singh being fielded from Tamil Nadu with its support.

DMK president M K Stalin announced that the third seat was being allotted to ally MDMK, in line with its pre-poll agreement with the Vaiko-founded party.

According to a statement from Stalin, party trade union leader M Shanmugam and senior advocate P Wilson are the nominees for the biennial election, slated on July 18.

"The other seat is being allotted to MDMK as agreed upon earlier," Stalin said.

The DMK had agreed to allot one Rajya Sabha seat to the MDMK as part of their pre-poll agreement for the Lok Sabha election.

Earlier, it was being speculated that Singh, earlier fielded from Assam, might be nominated from Tamil Nadu with the DMK's support.
