The Rajya Sabha has 12 nominated members in its total strength of 245. Of the 12 nominated members, there are seven vacancies at the moment.
Entry of Swamy, known baiter of the Gandhi family, into Rajya Sabha is being seen as a significant move.
Swamy on Friday took to twitter to thank his supporters and said, "as MP I will get the most important forum speaking on nations issues."
On the government’s recommendation, the President nominates members from those with special knowledge or having made their mark in literature, science, art and social service.
Currently, there are already five nominated members by the President: industrialist Anu Agha, lawyer K Parasaran, actor Rekha, cricketer Sachin Tendulkar and senior advocate KTS Tulsi - who were nominated by the UPA government.
