what does the secretary of state do in the uk
Secretary of State (United Kingdom) In the United Kingdom, a secretary of state (SofS) is a Cabinet minister in charge of a government department (though not all departments are headed by a Secretary of State, e.g. HM Treasury is headed by the Chancellor of the Exchequer).
Prime Minister of the United Kingdom The modern Prime Minister is also the leader of the Cabinet. A convention of the constitution, the modern Cabinet is a group of ministers who formulate policies.[24] As the political heads of government departments Cabinet Ministers ensure that policies are carried out by permanent civil servants. Although the modern Prime Minister selects Ministers, appointment still rests with the Sovereign.[25] With the Prime Minister as its leader, the Cabinet forms the executive branch of government.[note 2]
