Explain how the Prime Minister can control the Cabinet. 
While the Prime Minister is certainly the most visible and seemingly powerful member of Government, there is another element to make sure they don't have to govern alone. This is the Cabinet, a collection of up to 23 Ministers chosen by the Prime Minister. Although supposedly only “Primus inter pares”, the Prime Minister enjoys a variety of powers that allow him or her to control cabinet. Writers such as Richard Crossman in the 1960s and Tony Benn in the 1980s (both former labour ministers) spoke of the increasing dominance of the Prime Minister within cabinet. They argued this was because of the centralisation of party machines and the civil service in the hands of the Prime Minister. Since then the media has further increased their attention on the Prime Minister. Cameron exercises more power over his cabinet now than ever before, because this is the first time he has had an 100% conservative cabinet.
