Telangana Rashtra Samithi fielded P Dayakar and it has appointed state ministers as in-charges for the assembly segments falling under the parliamentary constituency.
In addition to the state ministers who campaigned vigorously in favour of the party nominee, TRS president and Chief Minister K Chandrasekhar Rao has also addressed a public meeting.
The main opposition Congress, which sought to salvage its prestige following the drubbing in last year's election despite "delivering" on the separate statehood demand, suffered an early setback with its candidate S Rajaiah having to go to jail following the deaths in mysterious circumstances of his daughter-in-law and three children at his home in Warangal.
Overcoming the embarrassment, Congress ran a determined campaign with senior leaders like Sushil Kumar Shinde, Meira Kumar, Ghulam Nabi Azad, AICC General Secretary (in-charge of party affairs in Telangana) Digvijay Singh and Rajasthan Congress chief Sachin Pilot canvassing for the party candidate.
BJP fielded an NRI medical professional P Devaiah on behalf of the NDA. Union Minister Bandaru Dattatreya, Hansraj Gangaram Ahir, Telangana BJP president G Kishan Reddy and party MLAs canvassed for the BJP candidate.
The Election Commission has made elaborate arrangements for the poll.
