 The House of Lords, the upper chamber of the British Parliament, is officially referred to as 'the Lords Spiritual and Temporal' in Acts of Parliament.  The House of Lords debates legislation proposed by the House of Commons before it is passed.  Unlike the Commons, the Lords are not elected, but are selected by inheritance or appointment, or in the case of the Lords Spiritual by ecclesiastical roles within the established church.  The Lords Spiritual are comprised of 26 senior bishops of the Church of England with the remainder (the number is not fixed) making up the Lords Temporal.

Traditionally the ceremonial dress for the Lords is a scarlet cloak trimmed with miniver (any white fur, but especially ermine).
