The ruling Bharat Rashtra Samithi (BRS) is struggling to retain the bellwether Andole constituency in Sangareddy district, with Congress giving a tough fight through its ‘Marpu Kavali’ campaign. Andole has consistently elected an MLA from a party that has formed the government 12 out of 14 times in united Andhra Pradesh and Telangana, having gone to polls since 1957.
