Raghav Chadha's Bold Challenge to Kejriwal

Raghav Chadha's bold challenge to Kejriwal is a legal coup, not a mutiny

Chadha and six AAP Rajya Sabha colleagues used the Tenth Schedule's two-thirds merger rule to defect to the BJP on April 24, 2026 — a legally engineered raid aimed at Punjab 2027.

On April 24, 2026, seven of the Aam Aadmi Party's ten Rajya Sabha members — led by Raghav Chadha, Arvind Kejriwal's one-time strategist and the party's most polished national face — walked into BJP headquarters and merged their bloc with the ruling party. The number 7 is not coincidental. It is the exact two-thirds threshold in Paragraph 4 of the Constitution's Tenth Schedule that immunises defectors from disqualification. Chadha's "challenge" to Kejriwal is not a personality feud; it is a surgical, statute-perfect operation to gut India's last credible non-BJP national opposition party — and to hand the BJP the Sikh-facing lieutenant it lacks for the 2027 Punjab assembly election.

That is the story worth telling. The wires have run the drama — the "Dhurandhar-style" video rebuttals, the "silenced not defeated" tweets, the mutual accusations of cowardice. Underneath the theatre sits a colder question: who benefits, and how was this legally engineered? The answer implicates Kejriwal's own weakness after losing Delhi in February 2025, the BJP's north-Indian succession problem, and a 40-year-old constitutional workaround that Indian courts have repeatedly warned Parliament to fix.

The mechanics: how seven MPs escaped Paragraph 2

The Tenth Schedule, added to the Constitution by the 52nd Amendment in 1985, disqualifies any legislator who "voluntarily gives up" party membership. Paragraph 4, however, exempts a merger when "not less than two-thirds of the members of the legislature party" agree to it. According to the parliamentary research service PRS India, the provision was tightened by the 91st Amendment in 2003 precisely to prevent one-third splinter groups from switching sides, as had happened in Goa and Haryana.

Chadha's group did the arithmetic and hit the number on the nose. Ten AAP Rajya Sabha MPs, seven signatures — Chadha, Sandeep Pathak, Ashok Mittal, Vikramjit Singh Sahney, Harbhajan Singh, Rajendra Gupta and Swati Maliwal. "Using the provisions of the Constitution of India, more than two-thirds of AAP's Rajya Sabha MPs have merged with BJP," Chadha wrote on X after the joint press conference, as BBC Hindi reported.

AAP's Rajya Sabha leader Sanjay Singh has since written to Chairman Jagdeep Dhankhar demanding disqualification of at least three MPs — Chadha, Mittal and Pathak — arguing that a merger of a "legislature party" of a national party is not permitted when the underlying "original political party" has not itself merged. That legal argument, though textually plausible, has almost no precedent going its way. As the constitutional scholarship compiled by PRS notes, "the two-thirds merger provision" has been used across state assemblies for two decades with disqualification petitions almost universally dismissed or left pending indefinitely.

The Observer Research Foundation, reviewing the record, concluded bluntly in an ORF analysis that the anti-defection regime is now "more in breach than in practice," with speakers and chairmen acting as "political animals" who delay adjudication until the political moment has passed. Chadha's team is betting on precisely that inertia.

Why Kejriwal was vulnerable now

The defection did not fall out of the sky. It sits on the ruins of AAP's February 2025 rout in Delhi, when the BJP took the capital after 27 years and Kejriwal himself lost the New Delhi seat, as BBC News reported at the time. Manish Sisodia, Saurabh Bhardwaj — the party's core Delhi bench — all went down. Al Jazeera captured the mood at the time: "BJP has the system sewn up."

After that loss, Punjab was AAP's only surviving state government and its only remaining route back to national relevance. Kejriwal's political capital collapsed, and with it his ability to police the ambitions of his younger lieutenants. Chadha, sidelined during Kejriwal's near-six-month jail stint in the excise policy case in 2024 — he was in London for medical treatment — had been reading the room ever since.

The break became public on April 3, 2026, when AAP replaced Chadha with Ashok Mittal as Deputy Leader in the Rajya Sabha and, according to PTI wire copy carried by BBC Hindi, wrote to the Rajya Sabha Secretariat asking that Chadha not be granted speaking time. That is an extraordinary request from a party against its own MP. Former Delhi chief minister Atishi told The Indian Express that Chadha "is not willing to fight the fight that needs to be fought in the country today." Chadha's public reply, borrowing a line from the film Dhurandhar, was "Main ghayal hoon, isliye ghatak hoon" — I am wounded, therefore lethal. Three weeks later he took six colleagues with him.

The real prize is Punjab 2027, not Delhi

Read the geography of the seven defectors and the strategy declares itself. Six of the seven Rajya Sabha seats being carried across are from Punjab; only Swati Maliwal represents Delhi. AAP holds 92 of Punjab's 117 assembly seats after its 2022 landslide, in which Chadha, as co-in-charge of the state campaign, was central. The party's ground game there was built on the two men now sitting in the BJP tent — Chadha and party general secretary Sandeep Pathak.

The BJP's Punjab problem is well-known: the party has never crossed single digits in the assembly, has no credible Sikh face, and lost its natural ally the Shiromani Akali Dal over the 2020 farm laws. Political scientist Hemant Atri, quoted by BBC Hindi, argued that none of the defectors is CM material, but that the BJP is trying to run in Punjab the same "Sikh versus non-Sikh, Hindu-consolidation" play it has used with Jats in Haryana and Marathas in Maharashtra. Chadha — Delhi-born, London-educated, Hindu — is the useful non-Sikh Punjabi face that the BJP has been unable to grow organically.

The move began paying immediate dividends. Within 72 hours of the merger, Union Home Minister Amit Shah tasked Chadha with a 50-district Punjab tour, according to BBC Punjabi, positioning him as the party's principal campaigner ahead of the 2027 vote. Congress's Punjab president Amarinder Singh Warring, cited by BBC Punjabi, told reporters his party had "known for a long time — since Kejriwal was arrested and Chadha was in London" — that this day was coming.

Who wins, who loses

The BJP wins twice over. First, it gains a Rajya Sabha bloc: with only 98 of 245 seats in the upper house on its own, according to the ORF's 2025 assessment, the party has relied on regional allies and money-bill workarounds to move legislation past the revising chamber. Seven fresh AAP defectors take the NDA closer to comfort. Second, it gains an on-air face for Punjab — a state that has resisted BJP penetration for four decades.

AAP loses its bench, its brand, and its plausible national future. The party website's line — that Chadha "did not choose politics, politics chose him" — now reads as a warning label. Post-defection, AAP has three Rajya Sabha MPs, no state outside Punjab, and a founding leader whose own constituency rejected him fifteen months ago. Punjab chief minister Bhagwant Mann, addressing reporters on April 24, called the seven "gaddaars" — traitors — and insisted his government's welfare model would carry AAP through 2027. That is the last card AAP has left to play.

Congress is the awkward third-party winner. In Punjab it becomes, by default, the natural non-BJP repository for anti-incumbency votes, especially in the state's Hindu-belt urban seats where AAP's collapse leaves a vacuum. Congress spokespersons quoted by BBC Punjabi argued that if the "pendulum swings" in urban seats, 2027 could deliver a Congress revival. Whether the party can execute is a separate question; the opportunity, at least, is real.

The constitutional afterlife

The largest second-order effect sits outside partisan politics. Every high-profile use of the two-thirds merger provision — Congress in Goa 2019, Congress in Madhya Pradesh 2020, Shiv Sena in Maharashtra 2022, and now AAP in the Rajya Sabha in 2026 — hardens the case that Paragraph 4 has become a driver of instability rather than its cure. The ORF's occasional paper on Rajya Sabha reform recommends that anti-defection rules be dropped altogether for the upper house, or restricted to no-confidence and money-bill votes. Chadha's operation is now Exhibit A for either argument — depending on which side wants which reform.

The Rajya Sabha Secretariat is now sitting on Sanjay Singh's disqualification petition. If Chairman Dhankhar refers it to the privileges committee, the case could take months; if he dismisses it, expect a Supreme Court writ under the Kihoto Hollohan line of precedent. Neither path realistically strips the seven of their seats before Punjab votes.

Diplomat View

The forecast, plainly: Chadha's defection will be judged not by Rajya Sabha arithmetic but by whether he can deliver even 15 to 20 Punjab assembly seats to the BJP in 2027 — a task no BJP campaigner has achieved in four decades. If he does, he will be the party's next northern star and a plausible Punjab CM candidate; if he does not, he becomes the highest-profile parking-lot defector of the decade, another Jitin Prasada or R.P.N. Singh with better English. The base case is somewhere in between: BJP crosses 10% vote share in Punjab for the first time in a straight fight, hurts AAP without displacing it, and Congress becomes the accidental beneficiary as the state fractures three ways. What would falsify this call: a formal AAP-Congress alliance for 2027, which would consolidate the anti-BJP vote and make the Chadha play a wasted trade. Watch for that alliance signalling from Kharge and Mann's camps between now and December 2026.

What to watch next

• Rajya Sabha ruling: Chairman Dhankhar's decision on Sanjay Singh's disqualification petition against Chadha, Mittal and Pathak — no statutory deadline, but expected before the monsoon session ends in August 2026.
• Punjab byelections: any assembly seat that falls vacant before 2027 becomes a Chadha test case; the BJP will contest it as a referendum on the merger.
• AAP-Congress talks: whether Mallikarjun Kharge and Bhagwant Mann move toward a pre-poll pact for the 2027 Punjab assembly election, currently ruled out but under quiet pressure from state-level Congress leaders after the merger.

The Bottom Line

Raghav Chadha's revolt against Arvind Kejriwal is not a personality feud — it is a legally engineered raid on the Aam Aadmi Party's Rajya Sabha bloc, timed to Kejriwal's post-Delhi weakness and aimed squarely at the BJP's four-decade failure to crack Punjab. If Chadha delivers even a mid-double-digit seat count in the 2027 Punjab assembly election, the two-thirds merger provision of the Tenth Schedule will have been rewritten in practice as a licence to disassemble opposition parties from the top. That, not the video clips and the Dhurandhar quotes, is why this story travels.
