why is the british parliament known as the mother of parliaments
The mother of parliaments (expression) The expression is often applied to the Parliament of the United Kingdom because of the adoption of the Westminster model of parliamentary democracy by many countries of the former British Empire.[2][3][4]
Term of office Because the government and Prime Minister are effectively indirectly elected through the Commons, the terms of Parliaments and MPs do not directly apply to offices of government, though in practice these are affected by changes in Parliament. While, strictly speaking, a Prime Minister whose incumbency spans multiple Parliaments only serves one, unbroken, term of office, some writers may refer to the different Parliaments as separate terms.[1]
