"Congrats Saina Nehwal on becoming World no 1 in Badminton; well deserved honour; best wishes for Indian Open Semi Final," Mukherjee wrote on his twitter handle.
PM Modi wrote, "The phenomenal accomplishments of @NSaina make us very proud. I congratulate her on being the World Number 1."
Saina scripted history by becoming the first Indian woman shuttler to reach the number one spot in world rankings, reaffirming her status as the country's most consistent performer in the international circuit.
Though the official rankings will be out only on Thursday next week, Saina was assured of her ascent to the top owing to the reigning world champion's 19-21 23-21 20-22 loss to third seed Thai Ratchanok Intanon.
Saina thus becomes only the second Indian overall to be world number one after Prakash Padukone had the distinction of being the numero uno men's badminton player.
