In which system of government is the executive and legislature fused?

The system of government where the executive and legislature are fused is the Cabinet system. In this system, the executive branch of the government is led by the Prime Minister and their Cabinet, who are also Members of Parliament.
The executive and legislative powers are intertwined in the Cabinet system. The Prime Minister and their Cabinet members are responsible for creating policies, proposing laws, and implementing them. They are not only political leaders but also lawmakers.
In the Cabinet system, the Prime Minister is chosen by the legislature. Generally, the leader of the political party or coalition that has the majority in the legislature becomes the Prime Minister. This means that the executive branch is directly accountable to the legislature and can be removed from power if they lose the confidence of the legislature through a vote of no-confidence.
The Cabinet system offers a quicker decision-making process. Since the executive and legislature are fused, the policy-making process is streamlined. The members of the Cabinet can propose and discuss policies directly in the legislature, making it easier to pass laws and implement them efficiently.
In summary, the Cabinet system is a form of government where the executive and legislature are merged. The Prime Minister and their Cabinet members lead both the executive branch and the legislative branch of the government. This system offers a faster decision-making process and direct accountability to the legislature.
