"After acceptance of Raja Bhaiya's resignation, Uttar Pradesh Governor B L Joshi today allocated his department to the Chief Minister," an official release said here.
Yadav is already holding portfolios of 66 departments, including home, personnel, planning, excise and sports.
Raja Bhaiya resigned today after he was booked for criminal conspiracy in the killing of DSP Zia-ul-Haq in Pratapgarh district.
Zia, posted as Circle Officer at Kunda town, was killed by a mob in Pratapgarh on Saturday when he had rushed there after a village head was shot dead over a land dispute.
