Rajasthan BJP leader Bhupender Yadav, another general secretary, has been made incharge of Bihar where assembly elections are due in November next year.
In Jammu and Kashmir and Jharkhand, which are going to assembly polls early next year or later this year, the party chief has appointed Avinash Rai Khanna and Trivendra Singh Rawat as incharge respectively.
Khanna, a leader from Punjab, was the incharge of J & K earlier too. General Secretary Prabhat Jha will take care of the party's affairs in Delhi where assembly polls are likely.
Srikant Sharma, BJP's national secretary who was incharge of the party's media cell, has been given the charge of Himachal Pradesh.
