Why the British Attitude Changed and the Cabinet Mission Plan of 1946 (ISC Class 12 History)
Updated 17 October 2026 · Fact-checked
After 1945 a Labour government, an exhausted British economy, new world powers hostile to empire, the INA trials and the 1946 naval mutiny made Britain ready to leave India. The Cabinet Mission (March 1946) proposed on 16 May 1946 a weak Union of India with three groups of provinces, a Constituent Assembly of 389 members and an Interim Government; the League and Congress read it differently, and it broke down.
Four pressures made Britain ready to leave India, so the 16 May 1946 Cabinet Mission Plan offered a weak Union, but League and Congress read it differently.

Understand Why Britain Changed Course and the Cabinet Mission Plan
What the syllabus asks. The syllabus asks for "reasons for change in the attitude of the British government after World War II" and for the Cabinet Mission's "aims and major provisions". Do not go beyond 1946 here; Attlee's Declaration and the Mountbatten Plan are in the next topic.
1. Why the British attitude changed.
1. *Change of government.* The Labour Party under Clement Attlee came to power in July 1945 and was more sympathetic to Indian independence.
2. *Britain was exhausted.* It was in debt (owing India large sterling balances), depended on American loans and could not afford to hold an empire by force.
3. *New world balance.* The USA and USSR opposed colonialism, and the United Nations Charter spoke of self-determination.
4. *The armed forces could not be relied on.* The INA trials (1945-46), the Royal Indian Navy mutiny at Bombay (February 1946) and unrest in the air force and army showed that loyalty was cracking.
5. *Mass upsurge.* Quit India, strikes, peasant movements and the reaction to the INA trials showed that India could not be governed against the people's will.
6. *A shrinking, war-weary civil service* had fewer officers to run the administration.
2. The Cabinet Mission (March 1946). Its members were Lord Pethick-Lawrence (Secretary of State for India), Sir Stafford Cripps and A. V. Alexander. Its aims were to reach agreement with Indian leaders on how to frame a constitution, to set up a constitution-making body, and to set up an Interim Government with the support of the main parties.
3. Major provisions of the Plan (16 May 1946).
1. The demand for a separate, sovereign Pakistan was rejected.
2. A Union of India of British India and the princely states would handle foreign affairs, defence and communications and be able to raise finance for them; all other powers would rest with the provinces and states.
3. The provinces would be placed in three groups: A (Hindu-majority provinces: Madras, Bombay, United Provinces, Bihar, Central Provinces, Orissa), B (Punjab, North-West Frontier Province, Sind) and C (Bengal, Assam). Groups could frame their own constitutions.
4. After the first general elections a province could leave its group, and after ten years any province could ask for the constitution to be reconsidered.
5. A Constituent Assembly of 389 members: 292 from the provinces (elected by provincial assemblies by proportional representation in three communities: General, Muslim and Sikh), 93 from the princely states and 4 from the Chief Commissioners' provinces.
6. An Interim Government, with all portfolios held by Indians.
7. India would be free to remain in or leave the Commonwealth.
4. Reactions.
- The Congress accepted the long-term plan, since it kept India united, but read grouping as optional and refused parity with the League in the Interim Government.
- The Muslim League accepted the Plan in June 1946, seeing compulsory grouping as the basis of Pakistan, but withdrew its acceptance in July after Nehru said that the Congress would be free to change the Plan in the Assembly. It called for Direct Action on 16 August 1946, which led to the Great Calcutta Killings.
- An Interim Government under Nehru took office on 2 September 1946. The League joined in October 1946 but obstructed its work and boycotted the Constituent Assembly, which first met on 9 December 1946.
Note that positions on grouping were interpreted differently by each side; present them as their claims rather than as settled facts.

Why Britain Changed Course and the Cabinet Mission Plan in real life
The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.
Why a compromise can mean different things to different parties
Suppose a neighbourhood committee passes a rule that "flats on each floor form a group" and then each floor decides its own parking rules, with a later review. One family reads it as optional and another reads it as compulsory.
Why does the rule cause a dispute?
Try it first, then show the solutionSolution
- The wording allows more than one reading.
- Each family chooses the reading that protects its interest.
- Trust falls when each fears that the other may change the rule.
Answer: Ambiguity combined with distrust leads to dispute; the Cabinet Mission's grouping clause was read as compulsory by the League and as optional by the Congress.
Memory hook: One clause, two readings.
Cost of holding on
Imagine a company that has been maintaining a distant branch for years, but now has heavy debts, fewer staff and a branch that no longer cooperates.
Why might the owners decide to hand the branch to its managers?
Try it first, then show the solutionSolution
- Costs are greater than the returns.
- Staff have lost interest in the old arrangement.
- Competitors disapprove of the arrangement.
Answer: When the cost of control exceeds its benefit and cooperation is gone, it is rational to leave; Britain in 1945-46 was in this position.
Memory hook: Cost over benefit, then exit.

Example 1: The Mission · 2 marks · Very short answerBoard level
Name the three members of the Cabinet Mission and state its aims in one sentence. [2]
Try it first, then show the solutionSolution
- Pethick-Lawrence, Cripps, Alexander (1 mark).
- To agree with Indian leaders on how to frame a constitution and set up an Interim Government (1 mark).
Answer: The members were Lord Pethick-Lawrence, Sir Stafford Cripps and A. V. Alexander. The Mission aimed to reach agreement with Indian leaders on the method of framing a constitution, to set up a constitution-making body and to form an Interim Government.
Example 2: Reasons for the changed British attitude · 4 marks · Short answerBoard level
Show how the armed forces and the changing world order helped to persuade Britain to leave India. Give four points. [4]
Try it first, then show the solutionSolution
- One mark for each of four reasons, with explanation.
Answer: First, the INA trials of 1945-46 aroused such public feeling that the loyalty of Indian soldiers to the Raj seemed doubtful. Second, the Royal Indian Navy mutiny at Bombay in February 1946, and unrest in the air force and army, showed that the forces could no longer be relied on to keep order. Third, the USA and USSR, now the leading powers, opposed colonialism, and the United Nations Charter spoke of self-determination. Fourth, Britain, in debt and dependent on American loans, could not afford to hold India by force, so a negotiated transfer was the practical choice.
Example 3: Provisions of the Plan · 6 marks · Long answerHarder board level
Describe the main provisions of the Cabinet Mission Plan of 16 May 1946. [6]
Try it first, then show the solutionSolution
- Rejection of Pakistan; Union with limited subjects (2 marks).
- Three groups and the right to leave (2 marks).
- Constituent Assembly of 389, Interim Government, Commonwealth (2 marks).
Answer: The Plan rejected the demand for a separate, sovereign Pakistan. It proposed a Union of India, including the princely states, which would handle foreign affairs, defence and communications and raise finance for them, with all other powers left to the provinces and states. The provinces were placed in three groups: A (Hindu-majority provinces), B (Punjab, NWFP and Sind) and C (Bengal and Assam), each able to frame its own constitution; after the first elections a province could leave its group, and after ten years any province could ask for a review. A Constituent Assembly of 389 members was to be elected (292 from the provinces, 93 from the states and 4 from the Chief Commissioners' provinces), an Interim Government of Indians was to be formed, and India could stay in or leave the Commonwealth.
Example 4: Why the Plan failed · 6 marks · Long answerHarder board level
The Cabinet Mission Plan was accepted by both the Congress and the Muslim League, at least in part, yet it did not succeed. Explain why. [6] (Analysis)
Try it first, then show the solutionSolution
- Different readings of the grouping clause (2 marks).
- Nehru's statement and the League's withdrawal in July (2 marks).
- Direct Action, Interim Government and the boycott of the Assembly (2 marks).
Answer: The Congress accepted the long-term plan because it kept India united, but understood the grouping clause as optional, and it refused parity with the League in the Interim Government. The League accepted in June 1946, seeing compulsory grouping as the basis of Pakistan, but withdrew in July when Nehru said that the Congress would be free to change the Plan in the Assembly. The League called for Direct Action on 16 August 1946, which led to the Great Calcutta Killings. Although an Interim Government took office under Nehru on 2 September, and the League joined in October, it obstructed the work and boycotted the Constituent Assembly of December 1946. Both sides therefore distrusted the other's interpretation and the Plan could not be worked.
Example 5: Source-based: a plan with two readings · 6 marks · Source-basedHOTS / competency
Read the extract (written for this page) and answer.
A mission of three British ministers proposed that provinces be placed in three groups and that, after the first elections, a province could leave its group. One party said this meant a province could decide for itself from the start; the other said the groups were compulsory until the first elections. Soon after, one party withdrew its acceptance.
(i) Name the mission and the year. [1]
(ii) Which party read the groups as compulsory and which as optional? [1]
(iii) Why did the party that read the groups as compulsory want them? [2]
(iv) Give two reasons why Britain was willing to offer such a plan in 1946. [2]
Try it first, then show the solutionSolution
- (i) Cabinet Mission, 1946 (1 mark).
- (ii) League compulsory, Congress optional (1 mark).
- (iii) Compulsory grouping would give Muslim-majority provinces a basis for a Pakistan in B and C (2 marks).
- (iv) Britain exhausted and indebted; army unrest; Labour government (2 marks).
Answer: (i) The Cabinet Mission of 1946. (ii) The Muslim League read the groups as compulsory, the Congress as optional. (iii) The League saw compulsory grouping of the Muslim-majority provinces in Groups B and C as the basis of a future Pakistan. (iv) Britain was exhausted and indebted after the war, and unrest in the armed forces and mass pressure in India meant it could not hold India by force; the Labour government was also more sympathetic.

Q1 · 2 marks · Very short answerBoard level
Which group did Bengal and Assam form in the Cabinet Mission Plan, and what could a province do after the first general elections? [2]
Hint
Punjab, NWFP and Sind; Bengal and Assam.
Answer
Bengal and Assam formed Group C. After the first general elections a province could leave its group.
Q2 · 3 marks · Short answerBoard level
What was the composition of the Constituent Assembly proposed by the Cabinet Mission? [3]
Hint
389 in all.
Answer
It would have 389 members: 292 from the provinces, elected by provincial assemblies by proportional representation in three communities (General, Muslim, Sikh), 93 from the princely states and 4 from the Chief Commissioners' provinces.
Q3 · 4 marks · Short answerHarder board level
Explain how the INA trials and the naval mutiny of 1946 changed British thinking about India. [4]
Hint
Think of the loyalty of the army.
Answer
The INA trials of 1945-46 aroused public feeling and showed that Indian soldiers might sympathise with those who had fought against Britain. The naval mutiny at Bombay in February 1946, with unrest in the air force and the army, then showed that the armed forces might not stay loyal. The British realised that they could no longer rely on the Indian army to hold India and must seek a settlement.
Q4 · 5 marks · Short answerHarder board level
Examine the response of the Congress and the Muslim League to the Cabinet Mission Plan. [5]
Hint
Read grouping differently; League withdrawal in July.
Answer
The Congress accepted the long-term plan because it kept India united, but read grouping as optional and refused parity in the Interim Government. The League accepted it in June 1946, seeing compulsory grouping as the basis of Pakistan, and withdrew in July after Nehru said the Congress would be free to change the plan in the Assembly. The League then called for Direct Action on 16 August 1946.
Q5 · 6 marks · Long answerHOTS / competency
"The Cabinet Mission Plan was a last chance to keep India united." Evaluate this view with evidence. [6] (Evaluation)
Hint
Weigh the united Union against the distrust of 1946.
Answer
There is support for the view. The Plan rejected Pakistan and kept a Union of India, which is why the Congress accepted its long-term form, and the League accepted it in June 1946. But its weak centre and the grouping clause, read in opposing ways, left both parties unsure that they would be safe. Nehru's July statement caused the League to withdraw, Direct Action followed, and the Interim Government became a scene of obstruction. A fair judgement is that the Plan offered a real chance but depended on trust that was no longer there in 1946.
