Telangana's KCR cited "political fragility" in the state as a reason for wanting early polls.
The CPI, TDP and Telangana Jana Samithi will enter into a pre-poll alliance in Telangana and would like to have the CPI(M) and Congress on board in the anti-TRS front, a senior CPI leader said Monday.
"We want first Telugu Desam Party (TDP), Communist Party of India (CPI) and Telangana Jana Samithi...we will join together, and we will invite the CPI-M also. And if there is a possibility, we would like to go with the Congress," CPI National General Secretary Suravaram Sudhakar Reddy told PTI.
Asked if such a pre-poll alliance was certain, the veteran Communist leader said, "Yes".
On whether there were any "feelers" from the Congress on joining the alliance, Mr Reddy said, "Not yet". Chief spokesperson of the Telangana Pradesh Congress Committee Sravan Dasoju said an electoral alliance with the TDP was "possible".
TDP supremo and Andhra Pradesh Chief Minister N Chandrababu Naidu has left it to the Telangana unit of the party to take a call on the issue of alliance.
"You collectively decide. You think and decide what is in the interests of Telangana and the party and let me know and I will cooperate," Mr Naidu said, addressing the general body meeting of TDP's Telangana unit on Saturday.
In alliance with the Bharatiya Janata Party (BJP) in the last elections, the TDP had won 15 seats but 12 of its MLAs defected to the Telangana Rashtra Samithi (TRS), making it a heavily depleted side.
A combative ruling TRS has already announced party candidates for 105 Assembly constituencies of the total of 119 constituencies. It had won 63 seats in the 2014 polls.
Significantly, TRS has so far not named candidates in four of the five segments held by the BJP.
Caretaker Chief Minister and TRS President K Chandrasekhar Rao has described Hyderabad Lok Sabha member Asaduddin Owaisi's All India Majlis-e-Ittehad-ul Muslimeen (AIMIM) as a "friendly party". AIMIM candidates had won from seven constituencies last time around.
The BJP has also made it clear that it would go it alone in the poll, the date of which is yet to be announced, amid indications that it may be clubbed with other four states slated to face election by the year-end.
