Why Great Britain with its centralized Parliament is an example of which type of government?

Great Britain, with its centralized Parliament, is an example of a parliamentary democracy. In this system, the executive branch derives its legitimacy from the legislature (Parliament) and is accountable to it. The Prime Minister, who is the head of government, is typically the leader of the majority party in Parliament, illustrating the close relationship between the legislative and executive branches. This structure allows for greater efficiency in law-making and governance, as the government is directly supported by elected representatives.
