Irish activist and fashion innovator Sinéad Burke has been included on the cover of British Vogue's September issue, often felt to be the magazine's most important issue of the year, and this year guest-edited by Meghan Markle. 

The Duchess of Sussex was confirmed as the guest editor in a post on her and Prince Harry's Instagram page, months after rumours of the collaboration began to surface. 

Bringing together 15 women for the cover, Markle and British Vogue Editor-in-Chief Edward Enninful created their list of changemakers in fashion, culture and politics, calling the women and the issue "Forces of Change". 

Burke is one of these women, no doubt having caught the Duchess's eye with her visionary campaigning for diverse and accessible fashion, as well as her eloquent advocacy on disabled rights. The Dublin-based activist featured in Vogue's list of the "25 most influential women" last year, and met Meghan during her visit to Ireland with her husband last summer. 

Also included in the list are Jacinda Ahern, the Prime Minister of New Zealand and a leading figure in politics, renowned for her compassionate and inclusive take on leadership; climate change campaigner Greta Thunberg; long-time activist and actress Jane Fonda; author Chimamanda Ngozi Adichie; and more. 

Enninful called the women "all titans in their respective fields", and were chosen "for the powerful and positive differences they are making in our world". 

Despite being the first person to guest edit the September issue of British Vogue, the Duchess chose not to appear on the cover, with Enninful explaining: "In the end, she felt that it would be in some ways a "boastful" thing to do for this particular project. She wanted, instead, to focus on the women she admires." 

According to the Instagram post, the Duchess worked on the issue for seven months, selecting "a diverse selection of women from all walks of life, each driving impact and raising the bar for equality, kindness, justice and open mindedness". 

Of the 16 panels on the striking black-and-white cover, one is a mirror, "so that when you hold the issue in your hands, you see yourself as part of this collective". 

As well as this, the issue will feature an interview with Meghan and former First Lady of the United States, Michelle Obama, a discussion between The Duke of Sussex and Dr Jane Goodall and stories from "grassroots organisations and incredible trailblazers", speaking to the Duchess's love of advocacy. 

Speaking of the issue, the Duchess said: "Guest Editing the September issue of British Vogue has been rewarding, educational and inspiring. To deep dive into this process, working quietly behind the scenes for so many months, I am happy to now be able to share what we have created." 

Speaking to Vogue, Enninful said: "To have the country's most influential beacon of change guest edit British Vogue at this time has been an honour, a pleasure and a wonderful surprise." 

Meghan is the latest royal family member to take on such a role, as Kate Middleton guest edited the Huffington Post in 2016 and graced the cover of British Vogue's centenary issue, also in 2016.
