Great Britain is the official name given to the two kingdoms of England and Scotland, and the principality of Wales. 

• Great Britain is made up of:


• England - The capital is London


• Scotland - The capital is Edinburgh


• Wales - The capital is Cardiff.

Great Britain is very often, but incorrectly, used as a synonym for the sovereign state properly known as the United Kingdom of Great Britain and Northern Ireland or theUK for short. 

If you look at the full name of the UK, you will see that the UK includes Great Britain AND Northern Ireland. 

Great Britain is a political term which describes the combination of England, Scotland, and Wales, the three nations which together include all the land on the island. It is also a geographical term referring to the island on which the greater parts of England, Wales and Scotland are situated. 

I agree with you, Team UK would be better.
