The Union Cabinet on Thursday approved the creation of a new state of Telangana by bifurcating the existing state of Andhra Pradesh.
After the Cabinet meeting, Union Home Minister Sushilkumar Shinde told media, "The Cabinet approved the formation of GoM for creation of Telangana. Hyderabad will be the joint capital for 10 years."
India's ruling Congress party on July 30, approved a move to carve out the Telangana region of Andhra Pradesh as the 29th state of the country, giving in to a five-decade-long demand from supporters in a major decision ahead of 2014 elections.
Officially urging the government to take constitutional steps that will see the state's formation, the Congress Working Committee (CWC) passed a resolution following a meeting of the constituents of the ruling United Progressive Alliance (UPA).
The state, which is likely to take few months to be formed, is expected to have 10 districts, a population of 35.38 million and an area of 1.14 lakh square km and including Andhra Pradesh capital Hyderabad, which serve as a common capital for 10 years.
The Congress has 33 MPs from Andhra Pradesh.
As many as 19 of them are from the coastal Andhra and Rayalaseema regions to be included under Telangana state. They are opposed to the division of the state.
