The government has reportedly agreed to BJP's demands on amendments to the Andhra Pradesh Reorganisation Bill, 2013, and the Prime Minister during his meeting with the BJP leaders is likely to assure them that their concerns regarding justice to Seemandhra region will be addressed.
While BJP has made its stand clear by backing formation of Telangana, it has put conditions to support the bill, saying concerns of people from the Seemandhra region be addressed specifically in the legislation and the quantum of financial package to be given to it be spelled out.
The Telangana bill is likely to be tabled in Rajya Sabha in a day or two after the President accords his approval.
The Union Cabinet had cleared the bill on Friday and the government has sent it to the President for his approval before introducing the measure in Parliament.
Proceedings in both Houses of Parliament have continued to be disrupted over the Telangana issue ever since the session commenced on February 5.
The government wants to urgently clear the bill after having announced the decision to bifurcate Andhra Pradesh as this is the last session before elections are declared.
