He said naming of prime ministerial candidate ahead of the polls was a "new phenomena" but a name would emerge on the numbers that the country throws up after polls.
"Personally I'm of the view that this whole clamour for announcing a name is a new phenomena. If the Congress party is stumbling in doing what it has to do about who is their number one is because of the reality. You don't know what the country is going to throw up by way of numbers," Singh told CNN-IBN.
Singh's comments came a day after BJP chief Rajnath Singh without naming Modi said, "Our choice of prime ministerial candidate is obvious and it is now the turn of Congress."
On Thursday, Chhattisgarh Chief Minister Raman Singh had said it was too early for BJP to take a call on its prime ministerial candidate and a decision in this regard will be taken at an appropriate time.
