what is a parliamentary republic
A parliamentary system is a system of government in which the ministers of the executive branch are drawn from and accountable to the legislature, such that the executive and â¦ legislative branches are intertwined. In such a system, the head of government acts as de facto chief executive and chief legislator.n contrast to a presidential republic and the semi-presidential system, the head of state usually does not have broad executive powers as an executive president would, because much of those powers have been granted to a head of government (usually called a prime minister).
