Okay, this is my take on London in the Imperial Commonwealth (Unofficial, don't want to tread on your toes Flocc).
- The pink denotes 'Greater London'.
- The orange denotes 'the Imperial territory of London' or colloquially - 'Imperial London'. It is the political heart of the Imperial Commonwealth.
- The green denotes 'Westminster' and the political heart of the United Kingdom.
- The red denotes 'The City' and the financial heart of both the Imperial Commonwealth and the United Kingdom.
The whole area constitutes
'London', it is the most expansive city in the world, seeing as New York doesn't exist as it does in OTL in this ATL. It also holds a population 18 million - the largest in the world. It accounts for nearly 25% of the United Kingdom's GDP, and just around 4-5% of the Imperial Commonwealth's total GDP. OTL London has around 17% of the GDP of the UK being around $US550 billion, if we are to take this figure into ATL then the Imperial Commonwealth has a GDP of around $US13.75 trillion - slightly more than OTL European Union and United States.
London hosts many important international financial, political and military organs such as
'the United Nations',
'Imperial Monetary Fund' and
'the World Trade Organisation'. London is also hosts the military headquarters of the Imperial Commonwealth located alongside the Imperial Parliament. London being the capital of the Imperial Commonwealth is nearly nothing like OTL London, there are large sectors of London which have their own unique English, Dutch, Japanese, Indian and African characters and so on - kind of like Chinatown or Little Italy in New York.
London is officially part of the United Kingdom, and is represented as such in elections, however it is managed and ruled as a semi-autonomous region within the Imperial Commonwealth and the United Kingdom. Citizens of London elect their own mayor and council who run London day-to-day. However, if need be the Imperial Commonwealth can pass laws, measures and controls in the Imperial Parliament to take control of the day-to-day handling of London or certain issues, but in reality this rarely happens.
Okay, I'm done. Can't wait for the flaming.
