LONDON — Meghan, the Duchess of Sussex, on Monday shared in an editor's letter for the September issue of British Vogue that her aim is to “shine light in a world filled with seemingly daily darkness."

The biracial, American-born royal has faced withering criticism from some parts of the British press since marrying Prince Harry in May 2018. The letter accompanied by another letter from Vogue editor Edward Enninful appeared in an issue of the magazine Meghan guest-edited.

The former Meghan Markle, who was an actress before marrying Harry, interviewed former first lady Michelle Obama for the issue, which featured 15 women who are called the "forces for change" on the cover.

Included among them are New Zealand Prime Minister Jacinda Ardern, climate change activist Greta Thunberg and Laverne Cox, the first trans person to be featured on the cover of British Vogue.

More than half of the women on the cover are women of color.

In the letter, Meghan describes discussing with Enninful “how to pivot from a perspective of frustration to one of optimism,” and notes her “candid and heartfelt conversation” with Obama. The interview was released Monday.

The comments, as well as her choice of women to highlight, came strikingly close to political commentary for a member of the British royal family, who are traditionally apolitical — in public at least.

The cover also features a mirror, literally — “a space for you, the reader, to see yourself. Because you, too, are part of this collective,” Meghan writes.

She isn't the first royal to guest-edit a publication. Harry was the guest editor on BBC radio in December 2017 and interviewed his father, Prince Charles, along with former President Barack Obama. Kate, the Duchess of Cambridge, guest-edited the Huffington Post in February 2016 to highlight children's mental health.

Since getting together with Harry, Meghan has come under fire in the British media for being outspoken, as well as for the pricey renovations she and Harry made to their new home in Windsor, wearing expensive designer clothing, and even for holding her baby son, Archie, “awkwardly.”
