Orkney has been held by the Liberal Democrats at all elections since the formation of the Scottish Parliament in 1999, with the current MSP being Liam McArthur, who won the seat at the 2007 Scottish Parliament election.

Orkney is part of the Highlands and Islands electoral region; the other seven constituencies are: Argyll and Bute, Caithness, Sutherland and Ross, Inverness and Nairn, Moray, Na h-Eileanan an Iar, Shetland and Skye, Lochaber and Badenoch.

The constituency is protected in law due to its geographical separation from other parts of Scotland, and therefore its boundaries are not subject to review.

[3] In the House of Commons of the Parliament of the United Kingdom (Westminster), the council area is covered by the Orkney and Shetland constituency, which also covers the Shetland Islands council area.

[4] It contains all six of the Orkney Council wards: East Mainland, South Ronaldsay and Burray; Kirkwall East; Kirkwall West and Orphir; North Isles; Stromness and South Isles; West Mainland.
