Loaded London: why our nation's capital is home to more billionaires than any other city in the world
According to a 2015 World Cities Cultural Forum report, the Argentine capital has more bookshops per capita (25 for every 100,000 people)
than any other city in the world.
The system has about a million lines and a billion stations (more
than any other city in the world), most of which I've never been to, despite living in the city for years.
London hosts over 480 overseas banks, more
than any other city in the world, with over 100 of Europe's 500 largest companies headquartered there.
