A crossbencher is an independent or minor party member of some legislatures, such as the British House of Lords and in the Parliament of Australia. They take their name from the crossbenches, between and perpendicular to the government and opposition benches, where crossbenchers sit in the chamber.
Crossbench members of the British House of Lords are not aligned to any particular party. Until 2009, these included the Law Lords appointed under the Appellate Jurisdiction Act 1876. In addition, former Speakers of the House of Commons (such as Lord Martin of Springburn and Baroness Boothroyd) and former Lord Speakers of the House of Lords (such as Baroness Hayman), who by convention are not aligned with any party, also sit as Crossbenchers. There are also some non-affiliated members of the House of Lords who are not part of the crossbencher group; this includes some officers, such as the Lord Speaker, and others who are associated with a party but have had the whip withdrawn. Although non-affiliated members, and members of small parties, sometimes physically sit on the crossbenches, they are not members of the Crossbench parliamentary group.
An "increasing number" of Crossbenchers have been created peers for non-political reasons. Since its establishment in May 2000, the House of Lords Appointments Commission has nominated a total of 67 non-party-political life peers who joined the House of Lords as Crossbenchers.
