Under the United States Constitution, the Executive branch is operated and elected separately from the Legislative branch, the Congress. They interact with the Judicial branch, the courts, under the principle of separation of powers, placing checks and balances on the power of each branch. In some democratic governments, notably the United Kingdom, the Chief Executive (prime minister) and his cabinet are selected from within the legislative branch.
The principle of operation involves using a fan mounted in the top of the cabinet to draw a curtain of sterile air over the products that are being handled.

In a Parliamentary system, the Prime Minister appoints a cabinet, usually selecting from among parliamentary members of the PM's own party. Cabinet solidarity refers to the tradition that once decisions are reached in cabinet, they are supported by all members of the cabinet, regardless of their opinion before consensus. A breach (or breaking with) cabinet solidarity traditionally requires the offending cabinet member's resignation or firing.
He is the Prime Minister and nominal head of the government which works largely through the Cabinet. Somehow, the Cabinet agree what is to be done. Then, under collective Cabinet Responsibility, the whole Cabinet accepts the decision. The PM is solely responsible for selecting all Cabinet Ministers etc.
