The founder of Lonely Planet, the popular travel guide line, is leaving the company, although reasons why remain murky. An extremely brief Booktrade Info report says both founder Katharine Leck and Sales & Marketing Director Andy Riddle are both leaving but it doesn’t really say why, except that Leck’s position of “Global Publisher, Guidebook & Maps” is being “relocated back to Melbourne” from London, and “Leck has in turn decided not to move with the job.”
