Papa John’s, the third largest pizza delivery chain in the US, has announced the resignation of its international president Robb Chase. Chase, who joined the company last year, is leaving to join a private equity firm in his hometown of Toronto. David Flanery, the company’s chief financial officer, will serve as interim president of the group’s international division, until a permanent replacement for Chase is found. Nigel Travis, president and chief executive of Papa John’s, said the company was disappointed to lose Chase. He said: “We will continue to invest in our international development as we grow the Papa John’s brand worldwide.” The company currently operates some 3,000 sites in 49 US states and 29 countries. It plans to double its number of UK stores to 170 over the next three years.
