Great BritainGreat Britain is an island in the North Atlantic Ocean off the north-west coast of continental Europe, consisting of England, Scotland and Wales. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The island of Ireland, with an area 40 per cent that of Great Britain, is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago.
Sovereign stateA sovereign state is a state that has the highest authority over a territory. International law defines sovereign states as having a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. It is also commonly understood that a sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being recognised by other sovereign states.
Sphere of influenceIn the field of international relations, a sphere of influence is a spatial region or concept division over which a state or organization has a level of cultural, economic, military or political exclusivity. While there may be a formal alliance or other treaty obligations between the influenced and influencer, such formal arrangements are not necessary and the influence can often be more of an example of soft power. Similarly, a formal alliance does not necessarily mean that one country lies within another's sphere of influence.
