UK: parts, capitals

Great Britain and the United Kingdom are two different areas. Often, but incorrectly, people use Great Britain as a synonym for the United Kingdom of Great Britainand Northern Ireland. Actually the full name of the UK includes Great Britain
and Northern Ireland.

Great Britain describes the combination of England(capital-London), Scotland(capital-Edinburgh), and Wales(capital-Cardiff). These are the three nations which together include all the land on the island. It also shows the island(as a geographical term ), on witch the greater parts of England, Wales and Scotland are situated.
