The members of the parliament are free to present their views and express themselves, and no action would be taken upon them for anything said in the house.

The members of Lok Sabha represent their constituency and has concern related to it, so this makes their power wide ranging.

The Union Cabinet which comprises of members of parliament is accountable for its decisions. They make laws and control finances.

The main purpose of parliamentary privilege is to control the executive.
