This episode introduces the larger-than-life characters that populate the House of Lords, one of Britain's oldest, most idiosyncratic and most important institutions.

Episode two of the exclusive behind-the-scenes documentary returns to the House as the government threatens to trim the Lords' powers if they rebel again, but will they comply?

Brexit hits the Lords with a bang when they vote on leaving Europe and become the centre of the nation's attention. They also have their biggest ceremonial day of the year when the Queen pays her annual visit.
