The joint meeting of TRS politburo, MLAs and state executive would be held at the party office here to deliberate on the political strategy for the future.
The meeting comes against the backdrop of the ties between the two parties running into rough weather with the TRS taking exception to the Congress "poaching" on its leaders.
TRS president K Chandrasekhar Rao had announced that he would be willing to merge his party with Congress if the latter accepted the separate Telangana demand.
However, the strain in the ties came with TRS MLA G Aravind Reddy and its expelled MP Vijayashanti joining the national party last week.

"It is certainly in bad taste with the Congress party, while talking to us about a merger or an alliance, at the same time they go about poaching our sitting MLA Aravind Reddy... They also admitted one of our expelled MPs.
"Therefore, this is something the Congress leadership needs to understand, that if you want to be friends with TRS, you cannot be picking up people from TRS and expect us to be friends also," TRS MLA and Chandrasekhar Rao's son K T Rama Rao said here on Friday last.
