Krishna Murthy, who handles the revenue portfolio and Chinarajappa, who looks after the Home department, assumed charge at the Andhra Pradesh Secretariat.
Security of women would be a top priority, Chinarajappa said, since the Telugu Desam Party (TDP) had promised to set up a system to respond swiftly after receiving information about crimes against women.
Several other ministers, including Ayyanna Patrudu (Panchayati Raj), K Mrunalini (Housing), P Pulla Rao (Agriculture), P Sujatha (Women's Empowerment) and P Manikyala Rao (Endowment), have also assumed charge today.
