"So far we have not taken any decision on chief ministers of Maharashtra or Haryana," he said after a meeting of the BJP Parliamentary Board.
Singh said this to reporters' queries on the sidelines of Indian Women Press Corps foundation day function, where he reached immediately after the Parliamentary Board meeting.
He said BJP will look for alliance in Maharashtra where it got 122 seats in the 288-member Assembly, well short of absolute majority.
"Want to thank people in Maharashtra and Haryana for reinforcing faith in Prime Minister Narendra Modi. Our strength has gone up," he said.
The Parliamentary Board decided to send two observers each to Maharashtra and Haryana to decide on who will be the chief ministers.
