In the past, Bharti had bitterly resented elevation of Chouhan as Chief Minister and had left the party in a huff eight years ago.
Bharti and other newly-appointed members of BJP's national team from Madhya Pradesh were today welcomed at a function at the party office.
She recalled her close association with senior BJP leaders such as Vijayaraje Scindia and other "mentors".
"I may have left the building, but I was never emotionally away from the BJP's ideology of Ram and Hindutva," she said.
"Despite Madhya Pradesh being a land-locked state, it has progressed tremendously under Chouhan with its GSDP growth at 12 per cent and agriculture growth at 18 per cent which are no mean achievements," she said today.
She said, "I am sure Chouhan, on his own, would easily win 150 seats in Madhya Pradesh and it is now our responsibility to add to it. The BJP would definitely win 25-30 per cent more seats this time.
