Organised by Immediate Live, the team behind events like the BBC Good Food Show and London Art Fair, this new series is being brought to Kew in partnership with RBG Kew.

Portfolio Director at Immediate Live, Rachel Poletti-Gadd, said: "With a cracking combination of celebrity voices, topical themes and excellent conversation, all you need to bring is a good picnic, a comfy blanket and some great company."

Director of Commercial and Visitor Operations at RBG Kew, Adam Thow, added: "It's a rare and exciting opportunity to experience some of the UK's most recognisable voices in a beautiful outdoor setting."
