“Through this lens I hope you’ll feel the strength of the collective in the diverse selection of women chosen for the cover as well as the team of support I called upon within the issue to help bring this to light,” she added, “I hope readers feel as inspired as I do, by the ‘Forces for Change’ they’ll find within these pages.”

The issue also includes a “candid conversation between The Duke of Sussex (Prince Harry) and Dr Jane Goodall, inspirational articles written by Brené Brown, Jameela Jamil and many others. Equally, you’ll find grassroots organisations and incredible trailblazers working tirelessly behind the scenes to change the world for the better.”

Markle is the first guest editor of the September issue in the magazine’s 103-year history. When Markle joined the Royal Family, she ended her lifestyle blog The Tig, a platform where she shared food, travel and other inspirations.

“After close to three beautiful years on this adventure with you, it’s time to say goodbye to The Tig,” she wrote at the time. “What began as a passion project (my little engine that could) evolved into an amazing community of inspiration, support, fun and frivolity. You’ve made my days brighter and filled this experience with so much joy. Keep finding those Tig moments of discovery, keep laughing and taking risks, and keep being ‘the change you wish to see in the world.’ Above all, don’t ever forget your worth – as I’ve told you time and time again: you, my sweet friend, you are enough. Thank you for everything.”

News of Markle and Obama’s conversation quickly went viral on Twitter, where people shared their enthusiasm for the issue.
