MALCOLM Glenn, regional managing director for Leo Burnett in Asia, has announced he will retire in June 1994. A 33-year veteran in advertising, Glenn plans to settle permanently in the US. He will be available to the agency on a consultancy basis. He joined Leo Burnett in 1989 and, under his stewardship, the agency's Asian network grew more than 30 per cent. One of the highlights was winning the Reebok account for the Bangkok office, which led ultimately to the shoe-maker awarding Burnett its entire US$140 million worldwide account. Mr Glenn was instrumental in establishing Burnett agencies in India, Korea and China.
