London venues are great places to do business because of the city's international standing, according to an expert.
The capital was ranked first out of 34 cities in Cushman and Wakefield's European Cities Monitor, which considers factors such as the transport links, quality of life and access to markets.
It is the 20th year in a row that London has come first, while Paris came second and Barcelona was in third.
Darren Johnson, chair of the London Assembly, said that while the rating was good news for London venues, there is "no room for complacency".
He explained that the city still needs to improve pollution levels, for example.
Mr Johnson suggested that the "huge range of languages spoken, its accessibility, its transport system [and] its international role in terms of markets" are just some of the aspects that make the capital city appealing to businesses.
"London has an awful lot going for it," he insisted, adding that the capital is also one of the best-known cities in the world for business.
