London is the top city of opportunity, beating New York by a "good margin" and Singapore, according to a new survey.

The report from leading accountancy firm PricewaterhouseCoopers says the capital finished first in "technology readiness, economic clout, and city gateway" which proves its place as a thriving economic powerhouse.

New York "continues to show strong consistency across most of the categories", says the report despite not finishing top of any of the criteria, which also included transportation & infrastructure, ease of doing business, cost, and demographics & liveability.

The Big Apple, however, finished in second place edging out Singapore, which jumped up four places.

PwC's report found that London is "technologically on top of its game" as it jumped from eighth place last year.

David Snell of PwC said: "London's reputation as an economic powerhouse is well established, and reinforced when you consider it is the second most successful city in the index for attracting foreign direct investment."

However, the city was given low marks for its cost of living -- the fifth highest out of the 30 cities studied -- and has the highest transport costs.

However, according to a study from YouGov, the rest of the UK feels it doesn't benefit from the capital's revitalised economy.

Only 24% of those surveyed who live outside London thought it benefitted their local communities, although 66% conceded that the capital's economic powerhouse was good for the national economy.
