The Northern Constabulary was the territorial police force responsible for Northern Scotland, covering the Highland council area along with the Western Isles, the Orkney Islands and the Shetland Islands, which make up most of the Highlands and Islands area. It was the police force covering the largest geographical area in the United Kingdom, equivalent to the size of Belgium, but was one of the smallest in terms of officers, with about 715 officers. The Constabulary was one of those amalgamated to form Police Scotland in 2013.
