The Bharatiya Janata Party (BJP) has achieved a significant victory in West Bengal, which is expected to enhance its representation in the Rajya Sabha starting in August 2029. This delay mirrors anticipated changes in Tamil Nadu, where the Tamilaga Vettri Kazhagam (TVK) is poised to debut in the Upper House, potentially securing at least three seats by June 2028. The BJP's growth in state assemblies is evident, with its MLA count rising from 773 in 2013 to 1,798 in 2026, positioning the National Democratic Alliance (NDA) closer to a two-thirds majority in the Rajya Sabha if it maintains momentum in key states like Uttar Pradesh, Uttarakhand, and Gujarat. Conversely, the Congress party is expected to see its strength diminish, currently holding 29 seats compared to the BJP's 113. Additionally, results from Kerala may reduce the Left parties' representation, although this is unlikely to impact the overall INDIA bloc significantly. The NDA's success in Puducherry will also aid in retaining its Rajya Sabha seat next October.
