Around 200 corporate event planners, event agency professionals and industry experts will gather in the venue's Medicinal Garden for the party where they will be served drinks and canapés upon arrival.
Guests will be given the chance to have a tour of the historic venue, enjoy a cheese masterclass and tasting and participate in a wine-matching demonstration. There will also be three BBQ stations and a dessert stand.
Richard Waddington, Chair of EMA, said: "This will be our second Summer Soiree and we had a number of interested venues but felt the RCP captured everything we were looking for with its great central location, unique setting and some great outdoor space with its amazing gardens.
"This will be a cross-industry event, with our members, who are exclusively in-house corporate event marketers, inviting special suppliers who have gone that little bit further for them. This is their way of saying 'thank you'.
"We will also have other senior representatives from across the industry who support Meeting Needs, the event industry’s charity, which will be doing a little fund-raising on the evening."
David Parker, meeting and events deputy director at The Royal College of Physicians, added: "We are delighted that EMA have chosen us to host their prestigious annual Summer Soiree. We pride ourselves on delivering top-quality events and with the event taking place in our magnificent medicinal garden, we could not be more confident in delivering an outstanding evening."
