Explain what limits there are to the Prime Minister’s control over the Cabinet. 
The Cabinet is one of the key parts of the British Constitution. It is simply a collection of Ministers (usually 20 -25) appointed by the Prime Minister, currently David Cameron, to form the Government. Each Minister is in charge of a Government Department. They will be held accountable for the performance of that Department when they are in charge. The Prime Minister is described in some constitutional sources as PRIMUS INTER PARES or FIRST AMONG EQUALS. This suggests that the Prime Minister is only as powerful as their Cabinet colleagues. In reality the Prime Minister can dominate the Cabinet proceedings by the tools at their disposal. However, while, there is no doubt Prime Ministerial power is usually dominant the Cabinet can prove very strong too and, given the right circumstances, can bring down even the most powerful Prime Minister. In examining the limits to the PM’s power, a good place to start is their limitations when selecting the Cabinet.
