What are the causes of London's cultural diversity?
Open boarders- free movement (e.g 250,000 french ppl live in London- it's France's 6th largest city!!)
FDI- UK has attracted over 30,000 jobs to London from overseas owned companies investing in software and finance sectors, UK is a leading receiver of FDI from India, Ireland, France, Australis, Canada
Deregulation-freedom to invest and transfer capital, no gov approval needed to set up offices for financial services.
(In UK banks can trade shares without having to use London Stock Exchange)
