Those opposing a strong Lokpal bill have been heard saying that
"Unlimited or supreme power cannot be vested in the lokpal to take action against the prime minister who is elected through an electoral process"
The people who run this country seem to be so unaware of the Indian Political system. The PM is elected to run the nation, not rule the nation. He is not a monarch. He is on a job to serve the nation, and the citizens as well as the law has every right to question him. (let's not forget, that our current PM is not even an elected representative of the people).
Ideally, an MP is supposed to represent the opinion of people of his constituency in the Parliament. But this is seldom done, we elect a member to represent us in the Parliament, but all he/she does is represent the strength of his party. As people we have only the power to vote, and this power is vested into the MP we elect. Once this is done, our power gets converted into the ruling party's power, and more often than not misused for their personal and party's benefit. They exploit the power for around 3.5 years.. and in the last 1.5 years, do something trivial, but exaggerated for their constituency, so that they are back "IN POWER" again in the next elections.
