Assertion: Some political parties in India felt that the Emergency was necessary to control the deteriorating condition of the country's politics.

Reason: CPI backed Congress during the Emergency, and believed that the opposition created the ruckus just to come into power.

The Assertion is correct but the Reason is incorrect.

Some other parties, like the CPI that continued to back Congress during the Emergency, also believed that there was an international conspiracy against the unity of India. It believed that in such circumstances some restrictions on agitations were justified. The CPI felt that the agitations led by JP were mainly by the middle classes who were opposed to the radical policies of the Congress party. After the Emergency, the CPI felt that its assessment was mistaken and that it was an error to have supported the Emergency.
