What was the impact of the promise made by the Viceroy to the Muslim Deputation on Morley-Minto reforms?

The Viceroy's promise had the following impact on Morley-Minto Reforms-

1. Morley-Minto Reforms of 1909 provided for separate representation of the Muslim Community in the Imperial Legislative Council as well as Provincial Councils.
2. The system of separate representation implied that 'communities' should serve as the basis for representation.
3. In other words, the Muslims would vote for Muslim candidates and the Hindus for the Hindu candidates.
4. Separate Electorates struck a fatal blow at the Unity of India.
5. Slowly but steadily they led to the Partition of India some forty years later.
