Darcy Willson-Rymer, who is set to step down as managing director of Starbucks UK in September, is to join Clinton Cards, the struggling high street retailer, as its new chief executive in an attempt to turn around its chain of shops. Willson-Rymer, who has been its managing director of Starbucks UK & Ireland since August 2008, will become the first chief executive of Clintons that has come from outside the Lewin family, which founded the chain in 1968. Under his leadership, Starbucks UK posted its eight quarters of unbroken like-for-like sales growth, refurbished many of its shops and increased its market share of the coffee market. Willson-Rymer, who will take up his new role at Clinton Cards in October, is being replaced as Starbucks UK managing director by Kris Engskov, the group’s current regional vice president of its US Pacific Northwest region.
