TI Media has announced that Marie Claire UK editor-in-chief Trish Halpin and managing director Justine Southall are to step down as the brand pursues its digital-first future. Trish was appointed editor of Marie Claire in 2009 and Justine joined the brand in 2011.

Marcus Rich, TI Media CEO, says: “Under Trish and Justine’s leadership, Marie Claire has continually set the agenda through its award-winning content, trailblazing campaigns and innovative brand extensions. Together with the Marie Claire UK team, they have shaped a legacy that will continue to inform this famous brand’s digital-first strategy. I would like to thank them both for the significant part they have played in the Marie Claire UK story and wish them all the very best with their future plans.”

Trish will leave TI Media at the end of September and Justine on 31 October.
