What is the difference in who exercises ‘Executive Power’ in the above two Constitutions of Nepal?

Answer: In Article 35 of the 1990 Constitution of Nepal, the power to rule the country, to set rules and to manage the country are all vested in the King of the country and the Ministers appointed under him.

However, Article 75 of the 2015 Constitution of Nepal states that the rules, governance and management of the country will be based on the laws mentioned in the Constitution of the country under the supervision of the Ministers.
