BJP’s Bengal win to boost Rajya Sabha strength, but only from 2029

The BJP’s strong showing in West Bengal is set to strengthen its position in the Rajya Sabha, but the gains will materialise only after the next parliamentary cycle, with the earliest vacancies from the state due in August 2029.

A similar lag is expected in Tamil Nadu, where the impact of recent assembly results will be felt from June 2028. The Tamilaga Vettri Kazhagam (TVK) is likely to make its Rajya Sabha debut then, potentially sending at least three members and altering the current balance by taking seats from the DMK, Congress and AIADMK.

The BJP’s expanding footprint across state assemblies continues to bolster its long-term prospects in the Upper House. The party’s MLA count has risen sharply from 773 in 2013 to 1,798 in 2026, strengthening the NDA’s chances of eventually approaching a two-thirds majority in the Rajya Sabha, provided it maintains its electoral momentum in key states such as Uttar Pradesh, Uttarakhand and Gujarat.

In contrast, Congress’ repeated electoral setbacks are expected to further erode its strength in the Upper House, where it currently holds 29 seats compared with the BJP’s 113.

Kerala’s results may reduce the Left parties’ representation in the Rajya Sabha next year, though this is unlikely to significantly alter the broader INDIA bloc’s numbers, as any losses for the Left could translate into gains for Congress.

Elsewhere, the NDA’s victory in Puducherry is expected to help it retain the Union territory’s lone Rajya Sabha seat when it comes up for renewal next October, while Assam’s outcome is unlikely to significantly change the current balance, with the BJP maintaining its position in the state.
