The report from CWT M&E is based on industry data and has London retaining its position despite uncertainty around Brexit.
Berlin was placed fourth, Barcelona drops to fifth and Milan breaks into the top ten in sixth.
Cologne, Stockholm, Amsterdam and Vienna complete the top ten.
“London and the UK continue to be strong for meetings and events,” says Ian Cummings, Vice President, EMEA, CWT Meetings and Events.
“The uncertainty over Brexit – and the resulting devaluation of the pound – has made the UK an even more attractive destination.”
The report also identified a number of up-and-coming meetings and events destinations including Manchester, Porto, Seville, Rome and Nice which “typically offer better values than the top-tier cities, along with an increasing number of competitive hotels and venues”.
