Black women including Bernardine Evaristo and June Sarpong will take over the Instagram accounts of 70 prominent white women, including Gwyneth Paltrow and Victoria Beckham, for a day in a campaign to amplify black female voices and work.

Launching on 1 October, the first day of Black History Month in the UK, the #ShareTheMic campaign aims to magnify black women’s lives, stories and cultural contributions by taking over the Instagram accounts of white women with large social media audiences, reaching a combined total of more than 175 million followers.

Booker Prize winner Evaristo will helm the Instagram account of CNN’s chief international anchor Christiane Amanpour, while Emma Dabiri, author of Don’t Touch My Hair, will take over Gwyneth Paltrow’s account. Other pairings include Vanessa Kingori, publishing director at British Vogue and one of the campaigner’s organisers, with Kourtney Kardashian; and entrepreneur Sharmadean Reid with makeup mogul Charlotte Tilbury.

The movement stemmed from a desire to put women’s relationships ahead of the racial injustice brought so sharply into focus in 2020 and to encourage all women to be a part of the solution, the organisers said. By sharing the stories and experiences of black women, the intention is to forge essential relationships and promote active anti-racism across different industries.

Following on from the success of June’s #ShareTheMicNow campaign in the US, Kingori and Stephanie Phair, chief customer officer at Farfetch and chair of the British Fashion Council, wanted to recreate the action of magnifying the stories of black women in the UK.

Kingori, who was British Vogue’s first female business lead and Condé Nast’s first and only black publisher, said she had never witnessed more meaningful, honest discussions about racial disparity as she has amid the challenges and tragedies of 2020.

“My relationships with so many friends and allies deepened this summer as we opened up and began truly discussing the black experience in the UK and worldwide,” she said. “Our aim is that this movement will bring some of these thoughts and reflections to a wider audience via the ultimate facilitators of change – women.”

Phair said: “Women are powerful. Women working together are irrepressible. Storytelling, sharing opportunities and creating personal relationships will be a powerful tool as we work towards a better future.”

Black Curriculum founder Lavinya Stennett hopes taking part in the campaign will raise awareness of the work her organisation is doing to decolonise education and deliver black British history in schools. She said there had long been a lack of recognition of the work that black women do, and a lack of space for it to be appreciated.

“We live in a society that doesn’t amplify black women’s voices and, more often than not when black women do speak up, they’re either called into question or they face so much ridicule,” she said, citing the experiences of black women in positions of visibility such as the MP Diane Abbott.

“It’s so important for us as women to come together to share and celebrate each other’s work,” Stennett added. “We have so much power when we’re able to celebrate each other – it uplifts us and actually boosts the incredible work that we do, which is for everyone’s benefit.”
