Gordon Ramsay Holdings (GRH) is to lose one of its most senior chefs, with the departure at the end of the month of Jason Atherton, chef-patron at London's Maze. The chef, who has been with GRH for nine years, five of which were at Maze, will remain a shareholder in the company and will continue to have “some involvement”, according to a spokesperson for GRH. It is not yet known what Atherton's next step will be, although he is said to be considering a solo project. Maze's current executive chef James Durrant will step up into his role on departure. In an interview with M&C sister title Restaurant magazine last month, Atherton said Ramsay had had “a huge impact” on his career. “He taught me how to run a restaurant and how to train a brigade to run my restaurant when I'm not there," he said. The Maze brand, which started in London, now has four restaurants - in London, New York and Capetown and there are plans to set up three more outposts, in Australia and the Middle East.
