London received 55 inbound projects last year, double the amount in Dublin, Paris, Frankfurt and New York, triple that of Hong Kong and Luxembourg and five times the number in Tokyo, the City of London Corporation Global Investment Report said.
When compared to eight other financial centres London received the highest number of financial services foreign direct investment projects last year and between 2013 and 2017, with the US, Sweden and China the leading the investment.

The UK is the second largest destination market for Switzerland, France and India, and is the third largest for investment from Spain, Germany, Australia and Canada, according to the report, which said London's air connectivity, business environment and cost effectiveness made it an attractive proposition.
Corporate and investment banking, concentrated in London, receives most of the investment but more jobs were created in retail banking, which is more evenly spread throughout the country.
