The London Declaration was a declaration issued by the 1949 Commonwealth Prime Ministers' Conference on the issue of India's continued membership of the Commonwealth of Nations, an association of independent states formerly part of the British Empire, after India's transition to a republican constitution.
The declaration was drafted jointly by V. K. Krishna Menon, a constitutional advisor to Prime Minister Jawaharlal Nehru, and Sir Norman Brook, the British Cabinet secretary. The declaration stated the agreement of the prime ministers to the continued membership of India in the organization after it becomes a republic. By that declaration, the Government of India had expressed its acceptance of the King as a symbol of the free association of its independent member nations and head of the Commonwealth.
