I included the picture of Vedic parliament.
1. Red: Emperor/Empress/both
2. Blue: Ministers
3. Saffron: Religious leaders of various Hindu Religions of Traditional Vedic(82%), Sikhism(2%), Jainism(2%), Arya Samajis(2%), Hindu-like Buddhist sects(1%) and other Hindu religions(3%).
4. Green: Intellectuals and Scholars
5. Yellow: Representatives of peoples' revolutionary councils, or JanSansads. JanSansad leaders are elected by consensus, they don't have any political power outside there rights in there respective JanSansads. They control maximun works and government is mostly in charge of military, religion and little central economic planning.
So many people are involved... lol. But most decisions are take by only red dot in center

Also, tell about your parliamentary structure too
