Prime Minister is the creation of a convention; Queen should appoint that person who appears best able to command the support of a stable majority in HoC; Prime Minister proposes Ministers (appointed by the Queen) and requires them to resign, decides to advise the dissolution of Parliament; decides about the allocation of government tasks among departments, presides and controls cabinet meetings, settles disputes among ministers, presides some some of the more important standing committees of the Cabinet (defence, economic strategy), supervises MI-5 and MI-6, principal spokesman of the country, has patronage powers;

Ministers of the Crown: holders of any public office in her Majesty´s Government in the UK; those who hold high political office, not mere officials or members of public boards, regulatory bodies and so on; all are appointed by the Crown on the advice of the Prime Minister;Every department must have a ministerial spokesman in the Commons; departments created by convention; 18-24 ministers (including the Leader of the HoC) are cabinet members; Government continues in Office even after dissolution of HoC, unless election results indicate loss of majority;

Ministerial Responsibility: resign if things go wrong; Ministers are responsible for their personal acts, the general conduct of their Departments and acts done or left undone; both politcal and legal;

Collective Responsibility: Cabinet is collectively responsible for everything it decides, Cabinet minority is bound, no public critisism, otherwise resign of leak; "who does not resign is absolutely responsible and has no right to state that he didn´t agree";

Theory: Cabinet government (primus inter pares); practically Prime Ministerial Government; Members of Government are Members of Parliament (Convention; but: HoL has no control over money bills ? no Lord PM);
