Launching on 31 March, the new campaign aims to celebrate women from diverse backgrounds and professions who all carry a strong sense of personal style, and who have achieved inspirational success.
The women in the campaign, shot by Annie Leibovitz, are actress Emma Thompson; singer, songwriter and human rights campaigner Annie Lennox; campaigner and life peer Baroness Lawrence of Clarendon; singer and songwriter Rita Ora; supermodel, activist and artist Alek Wek; chef, writer and broadcaster Rachel Khoo; designer Lulu Kennedy, and structural engineer and advocate for Technical Careers, Roma Agrawal.
The work will appear in print supported by digital, mobile, and outdoor activity.
Last month M&S unveiled its long-awaited new website, after seven years of running its commerce offering on technology provided by Amazon.
It came as M&S made its debut at London Fashion Week with its "Best of British" range, designed in house at the newly opened M&S Studio in Shoreditch, London.
