Which branch is most powerful in a parliamentary government?

In a parliamentary government, the executive branch is typically the most powerful, as it is drawn from the legislative branch and is directly accountable to it. The prime minister and their cabinet, who are members of the parliament, hold significant authority in shaping and implementing policies. This close relationship allows the government to maintain control over legislative processes, often leading to a dominance of the executive in decision-making. However, the effectiveness of this power can depend on the political dynamics and the presence of opposition parties.
