LONDON — As June approaches, London’s social calendar is getting busy again.

The Royal Academy of Arts on Wednesday announced the cochairs of this year’s summer exhibition preview party: broadcaster Clara Amfo, actor Helena Bonham Carter, designer Rejina Pyo, sculptor Conrad Shawcross, and entrepreneur Hikari Yokoyama.

They will cohost the 257th edition of the ticketed early summer bash on June 11, inviting leading figures across art, design, fashion, culture, business and technology to have a first look and buy artworks from the exhibition. The summer exhibition will then open to the public from June 17 to Aug. 17.

Rebecca Salter, president of the Royal Academy of Arts, said the annual event is a celebration of contemporary art and architecture, and a vital platform and support for the artistic community. Funds raised from the party will directly support the exhibiting artists and the RA’s charitable work, including training young artists at the Royal Academy Schools.

Pyo expressed her joy in cochairing the event, noting RA’s legacy of nurturing creativity, while Yokoyama applauded the institution’s continuous cultivation of a dynamic artistic community in London.

As the longest-running annual art exhibition in the world, mounted without interruption since 1769, this year’s summer exhibition is themed around the concept of dialogues.

According to architect Farshid Moussavi, who coordinates the fair alongside the exhibition committee members Tom Emerson, Stephanie Macdonald, Vanessa Jackson, Christopher Le Brun, Sikelela Owen, Helen Sear, Caragh Thuring and Richard Wilson, the summer exhibition is dedicated to “art’s capacity to forge dialogues and to afford us sensitivity towards societal concerns, such as ecology, survival, and living together.

“These dialogues can be between people of different races, genders, or cultures; between humans, all species, and the planet; or across different disciplines — art, science, politics, for example,” Moussavi added.

The RA summer party has also traditionally been a playground for London’s social elites to make bold fashion statements.
