The United Kingdom always confused me. It's made of multiple kingdoms right(Scotland, Whales, England?) hence the name right? Do they work like states in the US? Why is Northern Ireland part of it? What about the Falklands? Do they get represented in parliament? I read an article about some war hero in Australia and it made it seem like the Australian army was in cahoots with the UK's? What about New Zealand? What part do they have in this? Why does Canada still follow the Queen? Is that Cameron fellow still Prime minister? Does Scotland have any say on anything? When are your elections and at what intervals? Does England have any control over England? How the heck does it work? I know I misspelled Wales. I always hear it as refered to as England? Why is this the case???

That's another thing. What's up with the royal family? How can anyone support them? I mean, the ones they have now seem cool except for the Queen who seems like mean old arrogant woman. I like how the princes served in the military and such alongside their countrymen but I still don't support elevating one family over others just because they were born in it. The only way people should b of higher class is if they are wealthier not because of their heritage.

Canada and australia are common wealthy and the queen is their ceremonial figurehead

Common wealthy. Haha. Damn phone

What is the common wealth? What are the rammifications of being common wealth? Do thy have any representation in English parliament/ I thought they had their own parliaments? Do they lose any sovereignty from this?

GB (Great Britain) = England, Scotland, Wales

Obviously I did not know all these off by heart and Ihad no idea there were so many countries involved in making up our old 'empire'

As for all your other questions...you are asking for a LOT of info as the UKs history is vast.

No it's just held over from when they were part of britian

The UK is one kingdom (not several) but it's composed of several countries: England, Scotland, Wales and Northern Ireland, plus dependencies and overseas territories (islands).

There's a British parliament that represents them all, but Scotland, Wales and Northern Ireland have their own regional bodies. England does not have a parliament, because England represents such a high percentage of the UK's population the British parliament kind of represents England anyway (though polls show that most English people would like to have an English parliament).

I don't know much about the Commonwealth, but it's some sort of agreement beween countries that used to belong to the British empire. It has little practical purpose as far as I know.

Could Scotland theoretically leave the UK if they wanted to? Is it like a Union of countries akin to the European union only of the nations on the island or is it more like the US or perhaps a mixture of both???

I live in the UK by the way,  England rules Scotland, Wales and Northern Ireland, There's only one government in the UK which is in England, David Cameron is the Prime Minister of the United Kingdom. 

Scotland, Wales, and Northern Ireland are not independent countries.
