Topshop boss Sir Philip Green has said that the young fashion chain’s collaboration with supermodel Kate Moss had “lost that edge” and its “purpose”.

Speaking following the news last week that Moss’s three-year design partnership with the Arcadia owned chain would come to an end in October, Green said: “About two or three months ago, we came to the decision that it [the collaboration] had lost that edge, and we’d lost what our purpose was.

“It’s different now to when we started and probably became too overloaded. It wasn’t working. We all got too bogged down. We were trying to produce these big collections, but it was too difficult and we needed a rethink.

“We [Green and Moss] discussed it and decided this was the way to go. It isn’t a split. There are two of three very special projects we have in mind, which we will do as and when. They have to be unique, special and they have to have her stamp on them,” he told Grazia magazine.

When the supermodel launches her autumn range next month, it will her 14th and final full collection for the fashion retailer, although she is set to produce capsule collections for the store in the future.

When Kate Moss’ first collection for Topshop launched in April 2007, thousands of people queued outside Topshop’s flagship Oxford Street store to see a brief 12 second appearance from the supermodel in the shop window.

Moss is understood to have made around £3m from the partnership.
