"It is a very sad day for Andhra Pradesh. I am hurt and aggrieved at the way the decision has been rushed to bifurcate the state," Pallam Raju told reporters here.

The union cabinet Thursday formally decided to bifurcate Andhra Pradesh.

"I have decided that I should resign from the union council of ministers. I have sought an appointment and I will be tendering my resignation," he said.

He said that he had met the prime minister Thursday night and offered to quit but Manmohan Singh told him not to act in haste.
