Prime ministerial government is a government where the prime minister is dominant in terms of the executive. As the prime minister is, by definition, a member of a cabinet - this form of government is often a development from cabinet government. In true cabinet government the prime minister is primus inter pares (first among equals), where prime ministerial government necessitates the crossing of this boundary. An often cited example of prime ministerial government is the United Kingdom, where recent leaders such as Margaret Thatcher and Tony Blair, have exercised leadership which circumvents cabinet. Thatcher began using bilateral meetings with individual ministers to determine policy areas using cabinet to simply announce these decisions. Due to the extent of her victory, and her control over cabinet positions, ministers were not as ready to question her as they may have otherwise been.
