The principles of rule of law and Parliament is sovereign show the strengths of an unwritten constitution. An important aspect when deciphering between principles and constitutions is the fact that "constitutions may change "but principles remain-(Mahler 186). .
One of the most interesting components of Britain's political system is the fact that they are not federal; they practice a unitary system of government. Which is very different from other political systems (United States, Germany) because there is no "sharing of sovereignty between the national government and some intermediate level of government-(Mahler 186). This is significant because Parliament is routinely involved with everyday affairs. The institutions of government of Britain are as follows: the monarch is the official head of state, but the Prime Minister owns the real political power. The prime minister appoints his cabinet, which advises him on the issues (the cabinet is becoming more and more powerful). Above all, the government is accountable to the Houses of Parliament (Commons and Lords). The House of Commons, the lower house, has most of the political power (as with most lower houses). Political parties are imbedded in British politics. From organizing electoral choices to the selection of candidates in elections, it is suggested, "British government is party government-(Mahler 206). The Liberal and Conservative parties have dominated the scene, but the formation of the Liberal party generated representation in Parliament. In terms of voting, Britain practices a single-member district, plurality-voting system. The " first past the post- form of voting means it does not matter if a candidate has a majority of the votes. Rather, he must only have a plurality, or more votes than any other candidate. An election must be held at least every five years, but in essence, the prime minister decides when an election will be held, and can ask the monarch to dissolve parliament for new elections.
