The BJP-led NDA lacks the two-thirds Rajya Sabha majority needed to pass any Constitution amendment bill in the 2026 Monsoon Session. Despite allies Chandrababu Naidu's TDP and Nitish Kumar's JD(U) staying loyal, the coalition still falls short — forcing the BJP into back-channel diplomacy with regional parties it actively worked to defeat, including the BJD and YSRCP.

Here is the paradox nobody in the ruling coalition wants to say aloud: the BJP can win a confidence vote in its sleep, but it cannot change a comma in the Constitution without begging parties it spent crores to destroy.

As Parliament gears up for the 2026 Monsoon Session, the NDA government faces a structural wall that no amount of triumphalism about its Lok Sabha tally can paper over. A Constitution amendment bill — the highest legislative threshold India's democracy sets — demands not a simple majority but a two-thirds supermajority in both Houses. In the Lok Sabha, with roughly 293 seats, the BJP-led alliance clears that bar comfortably. In the Rajya Sabha, as News18 has reported regarding the government's ambitious legislative agenda this session, the arithmetic turns hostile.

The upper house operates on a staggered election cycle. Members serve six-year terms, and seats reflect the political geography of state assemblies at the time of election — not the current dispensation. Which means Rajya Sabha seats won by the BJD and YSRCP during their years of state-level dominance in Odisha and Andhra Pradesh are still occupied by their nominees, even though both parties suffered devastating electoral defeats in 2024 that the BJP itself engineered or facilitated.

The Naidu-Nitish Ceiling

On paper, the BJP's two most critical alliance partners — N. Chandrababu Naidu's Telugu Desam Party and Nitish Kumar's Janata Dal (United) — are reliable. They have been voting with the government, and the NDA whip holds for ordinary legislation. But for a constitutional amendment, reliability is necessary and grossly insufficient.

The TDP holds a handful of Rajya Sabha seats. The JD(U) contributes a similarly modest number. Together with the BJP's own tally — which, according to current Rajya Sabha composition data, hovers around 96–98 seats — the formal NDA bloc falls well short of the approximately 164 votes needed for a two-thirds majority in an effective house of 245. This is not a marginal deficit. It is a structural one, and it explains why the BJP's parliamentary managers are not making triumphant speeches about constitutional reform but are instead, according to political observers and veteran parliamentary correspondents, making discreet phone calls.

Political Pulse

The quiet diplomacy has a deeply ironic flavour, and the corridors of Parliament are alive with talk about it. The BJD's Naveen Patnaik — the man the BJP dethroned in Odisha in 2024 with a ferociously competitive campaign — still commands a bloc of Rajya Sabha members whose terms run until 2028 and beyond. The YSRCP's Jagan Mohan Reddy, similarly ousted in Andhra Pradesh in a contest where the BJP's alliance with TDP was the decisive factor, retains upper house seats that reflect his 2019 landslide, not his 2024 defeat.

The talk in political circles, per seasoned watchers of Rajya Sabha arithmetic, is that BJP floor managers have been quietly testing the waters with both camps. The pitch, insiders suggest, is transactional rather than ideological: support on specific bills, in exchange for — well, that is the part nobody will say on the record. But the speculation ranges from central largesse for pet projects to a softening of investigative agency pressure that both parties' leaders have publicly complained about. "The Rajya Sabha is where the ghosts of defeated allies come back to haunt you," a veteran parliamentarian was heard quipping — and it captures the absurdity perfectly.

What makes this especially delicate is that neither Patnaik nor Reddy has any formal reason to help the government. The BJD sat in studied neutrality during the 2024 elections, and Patnaik's personal humiliation at the BJP's hands in Odisha makes magnanimity unlikely without a very concrete incentive. Reddy, meanwhile, has been publicly hostile toward the TDP — the BJP's own ally — and any cooperation with Delhi would infuriate his own cadre unless the terms were extraordinarily generous.

(This reflects parliamentary corridor chatter and political observer speculation, not confirmed negotiation details.)

Why This Matters Beyond One Bill

The Constitution amendment question is not abstract. The government's legislative ambitions this Monsoon Session are significant. News18 has reported that even the proposed amendment to the National Anti-Doping Act, 2025 — a bill that on the surface seems technical and non-controversial — signals the Centre's appetite for legislative overhaul across domains. When the agenda escalates to matters touching federalism, reservations, or electoral reform — all areas where constitutional amendment bills have been floated or hinted at — the two-thirds barrier goes from inconvenient to existential.

India Herald's read of what is really driving this quiet diplomacy is blunt: the BJP has discovered that India's upper house is structurally designed to resist exactly the kind of centralised, majoritarian momentum the party has built in the Lok Sabha. The Rajya Sabha's staggered cycle is, by constitutional design, a brake — and in 2026, that brake is being applied by the very parties the BJP spent its political capital defeating.

This creates a fascinating and underreported dynamic. The NDA's real coalition, for constitutional purposes, is not the one that appears on the alliance letterhead. It is a shadow coalition — ad hoc, bill-by-bill, built on private negotiations rather than public solidarity. And the leverage belongs not to the allies who won alongside the BJP, but to the adversaries who lost to it and still hold the upper house seats that matter.

What Comes Next

Watch for three signals in the coming weeks. First, any sudden thaw in the BJP's public posture toward the BJD or YSRCP — a complimentary statement, a dropped investigation, a central scheme disproportionately benefiting Odisha or Andhra — will be the clearest tell. Second, observe whether the government introduces the Constitution amendment bill at all during this session, or quietly defers it to avoid an embarrassing floor defeat. Third, and most revealingly, watch how Naidu and Nitish react if they discover that the parties the BJP defeated are being offered more to cooperate than the allies who stayed loyal are receiving to remain.

That last scenario is the real landmine. Coalition management in India has always been a jealous business. The moment TDP or JD(U) leadership perceives that the BJP values the votes of its former enemies more than the loyalty of its current friends, the whip that holds the Lok Sabha together starts fraying at the edges.

The two-thirds majority is a mirage until the votes are actually counted on the floor. And in the Rajya Sabha of 2026, those votes belong to people the BJP tried very hard to make irrelevant — and failed, because the Constitution's own architecture keeps them in the room.

The question the ruling coalition must answer is ancient and uncomfortable: when you need two-thirds, and your friends give you only a simple majority, exactly how much are you willing to pay the people you called enemies six months ago?

Key Takeaways

• The BJP-led NDA comfortably crosses the two-thirds threshold in the Lok Sabha but falls significantly short in the Rajya Sabha, where roughly 164 votes are needed for a constitutional amendment.
• TDP and JD(U), the NDA's core allies, contribute a limited Rajya Sabha seat count that cannot bridge this deficit — making them necessary but insufficient for the supermajority.
• The BJD and YSRCP, both defeated in their home states in 2024 with BJP's direct or indirect involvement, retain substantial Rajya Sabha blocs due to staggered six-year terms — giving them unexpected leverage.
• The BJP's back-channel outreach to these 'frenemy' parties exposes a structural irony: the coalition that matters for constitutional reform is not the one on the alliance letterhead but a shadow, transactional, bill-by-bill arrangement.
• If TDP or JD(U) perceive that defeated rivals are being offered better terms than loyal allies, the broader NDA cohesion in the Lok Sabha itself could come under strain.

Frequently Asked Questions

Why can't the BJP pass a Constitution amendment bill with just its NDA allies?

A Constitution amendment requires a two-thirds supermajority in both Houses. While the NDA clears this in the Lok Sabha, its combined Rajya Sabha tally — BJP (~96–98 seats) plus TDP and JD(U) contributions — falls well short of the approximately 164 votes needed in a house of 245, per current composition data.

Why do BJD and YSRCP still have Rajya Sabha seats despite losing state elections in 2024?

Rajya Sabha members serve staggered six-year terms elected by state legislatures. Seats won during the BJD's and YSRCP's periods of state dominance remain occupied by their nominees until those terms expire, regardless of subsequent state election outcomes.

What could the BJP offer BJD and YSRCP in exchange for Rajya Sabha support?

Political observers speculate the inducements could range from favourable central government schemes for Odisha and Andhra Pradesh to a softening of investigative agency scrutiny that both parties' leaders have publicly complained about, though no confirmed details are available.
