"If they want to give Telangana, the last chance for them is passing a bill in the session to be held from April 22 to May 10," Rao said.
"In April, they have to approve it in Cabinet, send it to President and complete all that process. That means, Government of India has to come forward in April first week itself. If they don't do it in April first week, then it will be clear that they are not going to give Telangana. Then you will see earthquakes happening here and what not," he told reporters here.
The TRS president is expected to meet NCP Chief Sharad Pawar during his stay in Delhi. Pawar is a known supporter of separate Telangana demand.
Last week, TRS had moved a no-confidence motion against the Congress government in Andhra Pradesh for not accepting the separate statehood demand. The no-confidence motion, however, was defeated.
Chandrasekhar Rao, who once offered to merge his party with Congress if it agreed to form separate Telangana, had indicated that his party might look at NDA for association as BJP is also in the frontline of the separate statehood stir.
