There was no contest as there were only six candidates for six vacancies. There were some doubts whether Vaiko's nomination would be accepted after his conviction in a sedition case by a Chennai court last week but it was accepted since the sentence was for only one year.
All the candidates received their election certificate from the Returning Officer.
DMK President M K Stalin accompanied Shanmugham, Wilson and Vaiko when they received their certificates.
Ramadoss was allotted a seat by the AIADMK under an agreement both the sides had entered into during the recent Lok Sabha elections. Similarly, Vaiko was given the seat by DMK.
Vaiko makes a reentry into the Upper House after 26 years. He had already served three terms in Rajya Sabha. He had also been a member of the Lok Sabha.
