A Cabinet minister or Union minister is the person who commands utmost authority of the concerned ministry. He/she is appointed by the President following a consultation with the Prime Minister. When it comes to eligibility, the individual has to be a member of either of the two houses of the Parliament. A Cabinet Minister is treated as the head of a particular ministry such as Education, Health, Home, Foreign, etc.
Minister of State with Independent Charge
Sometimes a State Minister is given independent charge of ministries, which don’t have a Cabinet Minister to oversee the operations.It is to be understood that the power of the Minister of State is confined to the particular region, and it is his responsibility to take care of the state-centric functioning of a ministry. The Union Cabinet minister comes into picture when a bigger policy decision needs to be taken. Moreover, the PM may not always call all State Ministers to discuss issues, but only the Cabinet Minister.
