Telangana TDP received a jolt ahead of the GHMC polls with Cantonment MLA Sayanna joining TRS in the presence of Chief Minister K Chandrashekar Rao. So far, five MLAs from Greater Hyderabad have joined in TRS in the recent past. However, T-TDP leader Errabelli Dayakar Rao said Sayanna joining TRS is not a setback to party as cadre is strength for the TDP. While Greater Hyderabad party president Maganti Gopinath said no TDP leader has joined in TRS along with Sayanna. Meanwhile, Nara Lokesh has instructed the T-TDP leaders to ensure no defections take place in future.
