Not really.
Great Britain is not a country, it is an island - one of the two large islands which, together with around 1000 small islands make up The British Isles.
As such, Great Britain does not have a government.
The island of Great Britain contains England, Wales and Scotland, and these together with a part of the other large island (Northern Ireland) and most of the small islands, make up The United Kingdom of Great Britain and Northern Ireland.
The government of The United Kingdom is the British Parliament in Westminster, London.
Wales Scotland and Northern Ireland have their own, regional assemblies with fewer powers than the Westminster government.
There is no equivalent separate assembly for England.
Because "The United Kingdom of Great Britain and Northern Ireland" is rather cumbersome, it is often abbreviated to "Britain," "Great Britain," "GB" "The UK" or others but should not be abbreviated as "England."
Great Britain has a constitutional monarchy.
It isn't. Great Britain (or Britain) is part of the United Kingdom of Great Britain and Northern Ireland, so some people might refer to Britain OR the UK and mean the same thing. London is the capital city of the UK in the same way that Washington DC is the capital city of the US.
No. The UK consists of Great Britain and Northern Ireland. In many respects Northern Ireland has its own government.
There is no English representative body. England is a part of, but not the same as, The United Kingdom of Great Britain and Northern Ireland. The representative - ie elected - part of the UK Government is The House of Commons a part of the UK parliament.
Because they are known by both names, the United Kingdom & Britain. The UK and Britain are not exactly the same Great Britain is all the countrys that we own all over the world and the UK is england, scotland, wales and northern ire land or vice versa, but still hense why they say the United Kingdom of Great Britain.
Sometimes people mean them to be the same but Great Britain is in fact the island comprising the mainlands of Scotland, Wales and England while the United Kingdom contains all of Scotland, England, Wales and Northern Ireland.
Scotland is on an island called Great Britain. Great Britain consists of Scotland, England and Wales. Northern Ireland is not in Great Britain but it is part of the UK (the same country as Scotland)
Great Britain does not have a leader because it is not a country. The head of state of the United Kingdom is Queen Elizabeth II. The current head of government in the UK is David Cameron.
Great Britain is synonymous with Britain. It refers to the island of Britain, which is made up of three countries, England, Scotland, and Wales. The United Kingdom is the government of theses distinctly separate, but united countries. The United Kingdom also governs Northern Ireland. You can make a comparison to the UK and England/Scotland/Wales to the US federal government and US states, but it's not the same relationship.
