"The Union government should withdraw the bill from Parliament to do justice to Seemandhra people," said Parthasarathy.
He was speaking to reporters on the sidelines of the inauguration of a new building at the government hospital.
Parthasarathy demanded that members from all parties study the Telangana Bill in the detail and discuss it before taking a final decision on its passage.
The Bill was "introduced" in Lok Sabha on Thursday amid unprecedented turmoil that saw MPs from both sides of the regional divide slugged it out on the floor of the House.
Parthasarathy also accused BJP of playing a "double game" on creation of the new state by deviating from its earlier stand of backing the bill.
