In a series of tweets, Modi, who was close to Raje during her earlier term, suggested that BJP leader Om Mathur be made Chief Minister of Rajasthan.
Attacking Raje's aides, Modi, who is now in London, said "the lady is a wonderful person but she now surrounds herself with a coterie..."
Modi had earlier accused senior BJP leaders Arun Jaitley and Bhupendra Yadav of selling poll tickets ahead of 2014 Lok Sabha Elections.
