He said the NDA was committed to choosing a candidate who has genuine interest in the nation and probity in public life and who can fight against corruption.
When asked to name a common candidate, Rao said, "By naming the candidate in advance you will be killing the chance of that candidate to become the President."
On talks within the BJP circles about former President A P J Abdul Kalam's candidature for presidentship, he said, "So far BJP has not come out with any name."
