With uncertainty continuing over government formation in Tamil Nadu, five Congress MLAs from the state were camping in Hyderabad on Saturday in an apparent move by the party to prevent any poaching attempts. Congress MLA P Viswanathan from Melur, who was formerly the AICC in-charge of party affairs in Telangana, was leading the group of five MLAs during their stay in Hyderabad, party sources said. The Congress has already declared its support for TVK, and Viswanathan is likely to become a minister if a TVK government is formed, the sources added.
