Practically Ahmedabad had been the capital of Gujrat and can be called a parent city of the Gandhinagar capital city, which is a well planned new capital complex created at outskirts of the congested parent city (Ahmedabad).
If ADI is not capital og Gujrat, then Raipur is also not the capital of Chhatisgarh, it is Naya Raipur, which too has been created as well planned capital complex at outskirts of Raipur.
