A parliamentary system is a system of democratic governance of a state where the executive derives its democratic legitimacy from its ability to command the confidence of the legislature, typically a parliament, and is also held accountable to that parliament. For instance the government must gain a vote of confidence from the assembly, the assembly may grant to the government the power to make delegated legislation or the head of government is automatically a member of the assembly. With this, everyone is collectively responsible for all decisions made and enable a smooth administration of governance.
