Congress in Telangana likely to receive blow if rumours come true that former Minister Danam Nagender may join TRS soon. It is learnt that Danam had made an attempt to join TRS through K Keshava Rao in the past but could not get approval of the TRS chief KCR. Recently, TRS leader Talasani Srinivas Yadav met Danam at his residence. Sources said that Talasani met Danam only to invite him for Bonalu festival. But, the real intention is to make Danam to join TRS prior to Talasani going for by-poll contest from Sanathnagar Assembly constituency.
