प्रतीकात्मक पद या शोभा का पद

इस संदर्भ में विकीपीडिया की यह जानकारी गौरतलब है -
"In politics, a figurehead is a person who holds de jure an important title or office yet de facto executes little actual power, most commonly limited by convention rather than law. The metaphor derives from the carved figurehead at the prow of a sailing ship. Commonly cited figureheads include Queen Elizabeth II's[1][2] role as Queen of the United Kingdom, sixteen Commonwealth Realms and head of the British Commonwealth overall; she has an important office title, but no power over the nations in which she is not head of state. The Queen also holds all powers of state in her kingdoms, but rarely exercises them. Other figureheads are the Emperor Akihito of Japan, or presidents in some parliamentary republics, such as the President of Israel, President of Pakistan, President of Greece, President of Germany."
