Ganga rejuvenation was the pet project of Prime Minister Narendra Modi, and Balyan and his boss, Uma Bharti, seems to have not made any visible progress in it. India's almost Rs 20,000 crore plan to clean the holy Ganga river is badly behind schedule, with large stretches contaminated by toxic waste and sewage, forcing Modi to intervene.
Harsh Vardhan, who is heading the Ministry of Science and Technology, was charged to head the Ministry of Environment following the demise of Anil Madhav Dave in May. She has been keeping indifferent health for the past few months and reportedly wants to work for the Namami Gange project as well as work for the BJP.
The united AIADMK - comprising of the factions led by Chief Minister E Palaniswami and and former CM O Panneerselvam - is also expected to join the NDA. Karnataka would have assembly polls next year.
Sources added that in the upcoming reshuffle, the NDA's latest partner - Nitish Kumar's JD (U) - may bag at least one berth.
