London's stature is remarkable. Can anywhere else claim to be both an international focal point of such significance and so commanding a national capital?
Just before this year's UK General Election, listeners of US National Public Radio were told that it “completely dominates the political, cultural and economic life of the UK to an extent rarely seen elsewhere”.
New York might rival it as an economic hub – though London recently overtook its US rival in the Global Financial Centres Index (GFCI) rankings. But New York isn't at the same time the seat of political power in the US or home to the nation's central bureaucracy.
Paris dominates France, but lags behind its British counterpart in terms of international finance, sitting at 37th in the GFCI table.
No-one doubts London's pervasive economic influence. More than a third of global foreign exchange takes place every day in London.
The city is home to 251 overseas banks. UK financial services had a trade surplus of $71bn in 2013. London's GDP is equal to that of Saudi Arabia.
And in relation to the rest of the UK, London's dominance is especially striking.
The capital generates 22% of UK GDP despite accounting for only 12.5% of the UK population. According to the Centre for Economic and Business Research, it makes a net contribution to the Exchequer of an astonishing £34bn.
Inner London's GDP per head was 328% of the European Union average in 2010, compared with 70% in west Wales - the biggest gap in any EU state, said the European Commission's statistics agency Eurostat. Among the next eight largest UK cities, only one other, Bristol, has a GDP that is above the national average.
In 2013 it was estimated that in property terms London's top 10 boroughs were worth more than all of Northern Ireland, Scotland and Wales combined. London's housing stock is worth as much as Brazil's annual GDP, estate agents Savills reported in January 2015.
