The Cabinet Mission Plan of 1946 was a high-stakes diplomatic initiative launched by the British Government to transfer power to a single, united Indian nation. Led by Lord Pethick-Lawrence, Sir Stafford Cripps, and A.V. Alexander, the mission proposed a three-tier federal structure where the center would control only defense, foreign affairs, and communications, while provinces would hold all other powers. It also introduced a controversial "Grouping System" (Groups A, B, and C) to satisfy Muslim League demands without creating Pakistan. Although initially accepted by both the Congress and the Muslim League, mutual distrust and differing interpretations—specifically regarding the mandatory nature of the groups—led to its collapse. This failure prompted Jinnah to launch Direct Action Day, setting the stage for the violent partition of India.| Feature | Details |

The Last Roll of the Dice
By 1946, the British realized that holding onto India was no longer possible. The Indian National Army trials and the Royal Indian Navy mutiny had proven that the military—the backbone of the Raj—was cracking. Prime Minister Clement Attlee dispatched three of his best men to New Delhi with a clear mandate: find a way to transfer power peacefully and, if possible, keep India united.
The Cabinet Mission arrived in March amidst a political deadlock. The Indian National Congress wanted a strong central government for a unified India. The Muslim League, led by Muhammad Ali Jinnah, demanded a separate sovereign state of Pakistan. The mission had to bridge this unbridgeable gap.

The Blueprint: A Three-Tier Federation
On May 16, 1946, the Mission unveiled its master plan. It rejected the idea of a separate Pakistan, arguing that it would contain large non-Muslim minorities and disrupt the economy and military. Instead, it proposed a unique “Union of India” with three tiers:
- The Union: A weak central government controlling only Defense, Foreign Affairs, and Communications.
- The Groups: Provinces would be divided into three sections:
- Group A: Hindu-majority provinces (Madras, Bombay, UP, Bihar, Central Provinces, Orissa).
- Group B: Muslim-majority provinces in the North-West (Punjab, Sindh, NWFP, Baluchistan).
- Group C: Muslim-majority provinces in the East (Bengal, Assam).
- The Provinces: Individual states with full autonomy over all other subjects.
The genius—and the flaw—of the plan was that it gave the Muslim League a “Pakistan within India” through Groups B and C, while satisfying the Congress’s desire for a united country.
The Summer of Confusion
Initially, it seemed like a miracle had happened. Both parties accepted the plan. Jinnah saw the “Groups” as a stepping stone to Pakistan, while Congress viewed the “Union” as a victory for unity.
However, the devil was in the details. The Congress, particularly leaders from Assam and the North-West Frontier Province (NWFP), opposed the compulsory grouping. They feared that Hindu-majority Assam would be swallowed by Muslim-majority Bengal in Group C. Congress argued that provinces should have the right to opt out of their groups immediately. The Muslim League insisted that grouping was mandatory from the start.
The Press Conference That Changed History
The delicate house of cards collapsed on July 10, 1946. In a press conference in Bombay, the newly elected Congress President, Jawaharlal Nehru, stated that the Constituent Assembly would be sovereign and “would be free to change or modify the Cabinet Mission Plan as it thought best.”
Jinnah interpreted this as a betrayal. He believed that once the British left, the Congress numerical majority would tear up the guarantees given to Muslims. Furious, Jinnah withdrew the League’s acceptance of the plan on July 29.

Direct Action Day: The Point of No Return
Having lost faith in constitutional methods, Jinnah declared, “We shall have India divided or India destroyed.” He called for Direct Action Day on August 16, 1946, to achieve Pakistan. What was meant to be a day of protest turned into the “Great Calcutta Killings,” where thousands were massacred in communal riots. The violence spread like wildfire to Noakhali and Bihar. The dream of a united India died in the streets of Calcutta, and the road to Partition became inevitable.
The Interim Government
Despite the collapse of the long-term plan, the Mission managed to set up an Interim Government. On September 2, 1946, Jawaharlal Nehru took oath as the Vice-President of the Viceroy’s Executive Council (de facto Prime Minister). The Muslim League initially boycotted it but joined later in October. However, they entered the government not to cooperate, but to obstruct. The Finance Minister, Liaquat Ali Khan (League), famously blocked every proposal made by the Congress ministries, paralyzing the administration and proving that the two parties could not govern together.

Curious Indian: Fast Facts
- The “ABC” of India: The Grouping system (A, B, C) was the most unique feature of this plan. It was essentially a proposal to create sub-nations within a nation.
- Gandhi’s Instinct: Mahatma Gandhi was initially suspicious of the plan, famously asking to see the “convertibility clause”—the right of provinces to opt out. He advised Assam’s leader Gopinath Bordoloi to reject the compulsory grouping, predicting it would lead to their subjugation.
- The “If” of History: Many historians argue that had the Cabinet Mission Plan worked, India would have been a massive, loose federation today—potentially avoiding the Kashmir, Bangladesh, and nuclear flashpoints, but perhaps suffering from a perpetually weak central government.
- Wavell’s Breakdown: The Viceroy at the time, Lord Wavell, was so frustrated by the failure of the mission and the ensuing violence that he drafted a “Breakdown Plan” to withdraw British troops province by province, which London rejected before replacing him with Mountbatten.
Conclusion
The Cabinet Mission Plan 1946 was a brilliant intellectual exercise that failed the test of reality. It tried to stitch together a fabric that had already been torn by decades of mistrust. Its failure is a somber reminder that constitutional safeguards mean nothing without political trust. The rejection of this plan paved the way for the Mountbatten Plan, swapping a loose federation for a hard partition—a trade-off that defined the modern geography of South Asia.
