Power 50 2008: Tony Troy

Troy makes this year's Power 50 list not least for the high-profile acquisition of the eight-strong Hayley Conference Centres property collection for £358m back in May last year as head of Principal Hotels. At the time of the acquisition, Troy declared his stated aim was to keep the two brands on as separate but complementary entities, and the judging panel backed the nominations he received, highlighting his success in "running two distinct animals in the same race". Under Troy's stewardship, both sides of the business are set to extend into Europe, kicking off with Hayley's ninth property, the Château de Saint Just near Paris this September.
