The differences between the political executive and the permanent executive: Permanent executives are also known as “non-elected” executives whereas Political executives are “non-permanent” elected executives. While the former are not directly answerable to the people, the latter are accountable to the citizens who elected them.
Permanent executives usually have a very long term i.e., they do not leave office until and unless they retire, but political executives leave office as soon as their short term gets over.
Permanent executives are necessarily experts in their areas but political executives may or may not be experts in their areas.
Permanent executives get their designation and office through standard selection procedures whereas political executives get elected.
