Thirty-two ministers are expected to take oath. Governor ND Tiwari will administer the oath of office at his official residence.
But three ministers of the erstwhile YS Rajasekhara Reddy Cabinet refused to take oath out of a sense of loyalty to the late chief minister, who died in a helicopter crash on Wednesday, Sep 2.
Former ministers P Ramachandra Reddy, J Krishna Rao and Syed Ahmadullah said they were only willing to work as ministers under YSR's son Jaganmohan Reddy.
The All India Congress Committee (AICC) has maintained that the leadership issue in the state will be decided after the seven-day mourning period for the late chief minister is over.
It has said that it will depute central observers to meet MLAs and MPS in Hyderabad next week to decide on who will succeed YSR. It has warned the MLAs and MPs not to take any step that goes against the party's constitution.
