Highly-placed party sources said a section in the Congress feels that the merger before the assembly and Lok Sabha elections in Andhra Pradesh could be advantageous for BJP in Telangana.
The talk in the party is that the process of formation of Telangana is unlikely to be completed before the winter session of Parliament.
Assembly polls in Andhra Pradesh are scheduled along with the Lok Sabha polls, which are due by May next year.
TRS chief K Chandrasekar Rao, who had spearheaded the agitation on Telangana, has so far remained non-committal on the issue of merger despite the decision of the CWC on separate Telangana.
