TRS supporters celebrating party's win in the by-polls
In Andhra Pradesh, the movement that demands a separate state of Telangana has got a big boost. The party that has led that movement, the Telangana Rashtriya Samiti (TRS), has won four of the seven assembly seats at stake. Voting was held on Sunday and results are being counted today. Six of the seven seats are located in Telangana.
The TRS is headed by K Chandrasekhara Rao, also known as KCR. It has defeated the ruling Congress party and main opposition Telugu Desam Party (TDP) in Station Ghanpur, Kollapur, Adilabad and Kamareddy constituencies. Both the TDP and the Congress are accused by the Telangana movement of not supporting its demand of statehood.
The Nagarkurnool seat was bagged by N Janardhan Reddy, an independent candidate supported by the TRS. He was earlier with the TDP.
The elections were also positive for Jagan Mohan Reddy, who exited the Congress party to form the YSR Congress. His party's N Prasanna Kumar Reddy won in Kovur, the only seat the YSR Congress contested.
The BJP's Y Srinivas Reddy won from Mehbubnagar, the only seat it contested.
