The Waverley Group has announced major changes to the company's personnel and structure, including the departure of International Wine Services' (IWS) managing director, Allan Westray, following the integration of IWS into the Waverley Group. Ewen Cameron, Waverley Group chairman, said: This was always Allan's intention when the objectives of the original merger proposition were satisfied. This is now the case and Allan has decided to pursue other, personal ambitions.' Graham Threader, currently sales director, Waverley Wines and Spirits, will take over from Westray, with responsibility for group wine purchasing, UK packaging and international sales. IWS' highly-regarded winemakers, Kym Milne MW and Alastair Maling MW, are also leaving, to return to Australia and New Zealand respectively. Milne will retain some responsibilities' for IWS' winemaking projects and will act as an Australia-based consultant. Maling has taken up the position of Group Winemaker with Villa Maria in New Zealand. As a result of these changes, David Cowderoy will join IWS in September from Bottle Green, where he held a similar position, in order to assume general manager, UK responsibilities for IWS' winemaking projects worldwide,' said Cameron. John Weeks, currently based in South Africa, will be responsible for IWS projects in France, Spain and northern Italy. The company's trading structure will also change, with the management refocusing on two trading divisions - Old and New World wines. Cameron added: I must stress that it is essentially about management focus and that the business units will continue to trade as Italvini, Francevin and Pacific Wines.' Another change sees the arrival of Mark Jarman, formerly of First Quench, as IWS' senior commercial manager, Pacific Wines.
