Visit London commercial director David Hornby is calling on the UK C&I industry to sign a petition to save the US events market.
In a statement posted under his C&IT blog and in an email sent to industry leaders, Hornby raises concerns about the US congress developing policies that will inhibit companies bailed out by the Government from running meetings and events.
"As an industry, we obviously want corporates and brands to show empathy with current conditions, but we do not want draconian measures put in place by government both there and here in Europe that affect jobs, communities and businesses," the statement said.
"Site, MPI, PCMA, NBTA, DMAI and American Travel have been working hard to get them to rethink and lobby for self regulation.
"Obviously the consequences for London, the UK, Europe and our business in hotels, venues and the supply chain could be seriously affected. Many American companies, for example Bank of America and Wells Fargo, receiving this funding have European headquarters here in London so there would not only be an in-bound issue but also issues here on our soil.
"Please use your networks, online media activity to publish the petition below and encourage people to support it."
