Answer:

The PM is the linchpin of the Govt. of India. He has an edge over CoM in executive govt. because of the following reasons:

1. He is the head of govt. and all major appointments – political and permanent- are made under his guidance.

2. He is the Leader of Cabinet and any member having difference with the PM can be dropped if he does not change his mind.

3. He is the link between President and CoM.

4. He is also leader of the Parliament and in a Parliamentary form of govt. this very fact infuses great powers in him.

5. Though MEA executes the foreign relation, but it is the PM who is Chief spokesperson in foreign relations.

6. He is, more often than not, the leader of his political party and all the other members of CoM follow his command.

7. Since he is the Chairman of the Planning Commission of India, the ministries headed by other members of CoM can be greatly influenced by him through the planning process.
