Because the archipelago standing of the north-west coast of Europe is entirely dominated by the island of Great Britain, the largest and most populous island in the archipelago. This is a normal naming convention used elsewhere, such as the Hawaiian islands and the Greek islands.
That said, the name does prompt some controversy from those who object to the "British" title on grounds of the historical belligerence primarily of England.

THE ISLANDS OF THE ARCHIPELIGO WERE SO NAMED IN THE 19TH CENTURY AT A TIME WHEN THE United Kingdom WAS MADE UP OF Ireland, GREAT BRITAIN AND THE VARIOUS SMALLER ISLANDS.
AS A MODERN TERM IT IS UNACCEPTABLE TO IRISH PEOPLE AS IT INFERS THAT IRELAND IS A 'BRITISH' ISLE AND WOULD BE BETTER DISPLACED BY A MORE APOLITICAL WORD ( E.G. the Celtic Isles, or the Atlantic Isles, or the British and Irish Isles or .......).
IT OBVIOUSLY DOES NOT CAUSE PROBLEMS FOR PERSONS WHO CONSIDER THEMSELVES BRITISH BUT IS AN ANACHRONISM AND SHOULD BE REPLACED.
No, there is no single leader of the British Isles. What is called the British Isles has a number of countries and they each have their own leaders. The British Isles is a geographical reference, not a political one.
British Isles
The UK is not called the British Isles. They are two different things. The British Isles consists of the island of Britain, the island of Ireland and the many small islands around those two large islands. The British Isles is a geographical term. The United Kingdom consists of England, Scotland, Wales and Northern Ireland. All of the United Kingdom is in the British Isles, but there are many parts of the British Isles, such as the Republic of Ireland and the Isle of Man, that are not part of the United Kingdom. The United Kingdom is a political entity.
Pedantically, there is only one crown dependencies in the British Isles. There are actually three Crown Dependencies: the Isle of Man, Jersey and Guernsey. Jersey and Guernsey are collectively called the 'Channel Isles'. They are usually NOT considered part of the British Isles, because they are off the coast of France. That leaves only one Crown Dependency which is part of the British Isles, the Isle of Man.
No. Romania is a long way from the British Isles. It is in easter n Europe and the British Isles are in western Europe.
It is the Hebrides, comprising hundreds of islands off the northwest coast of Scotland. There are no such collection of islands off the northwest coast of England.
The North Sea.
Ireland is the smallest country in the British Isles
Ireland is not called the British Isle. The island of Ireland is beside the island of Britain. Collectively and with some of their surrounding islands, they are sometimes called the British Isles.
All of Great Britain is an island, even most of its territories. That is why they are called the British Isles.
There is around severn main cities in the british isles!
We are called The United Kingdom (U.K) or Great Britain.We share borders with Ireland,Scotland and Wales and these make up the countries that make up the British Isles..
