Hyderabad: Ten BRS corporators in the 28-member Boduppal Municipal Corporation have shifted to the Congress and tabled a no-confidence motion against BRS Mayor Samala Buchi Reddy and deputy mayor Kotha Lakshmi Ravi Goud. The corporation falls in Medchal constituency and multiple efforts by former minister and BRS MLA Ch Malla Reddy to retain them were in vain.
