Lok Satta Party of bureaucrat-turned-politician Jayaprakash Narayan is also likely to join the alliance of TDP and BJP.
Narayan is the sole MLA of his party in outgoing AP Assembly.
Meanwhile, the ruling Congress, having been spurned by TRS for merger or even an electoral alliance, is in talks with CPI for an electoral alliance.
CPI state secretary K Narayana said in Tirupati today that a decision on the issue is likely at the meeting of party's Telangana committee tomorrow.
TRS has held talks with CPI for alliance, but nothing concrete appeared to have come out of the exercise. As of now, it appears TRS may go alone in Telangana.
