Explanation:

Parliament - and the idea that it represents the voice of the whole nation - is one of the principal foundations upon which British citizens' rights are based. The origins of Parliament as a place of discussion stretch back to the Anglo-Saxon 'witan'Glossary - opens new window and beyond, but it was only in the 13th century that the modern form of Parliament began to take shape. Monarchs had always relied on assemblies of their great men for advice, and during the 13th century the king's most powerful subjects - lords, bishops and abbots - began to meet regularly as the Royal Council. This provided a forum for discussion of major issues, and subsequently formed the basis of the House of Lords.
