Leung is embarking on his own venture after resigning in June, with no further details available at this time, as he did not respond to requests for comment.
According to an Ogilvy spokesperson who confirmed the management shuffle, discussions are taking place internally, so Leung's exact departure timing in August is still to be confirmed.
Appointed general manager of [email protected] HK in December 2013 after joining last August, Leung's reputation has been "like the king of social media in Hong Kong", according to one source. However, industry sources told Campaign Asia-Pacific that they begged to differ, citing "tension" surrounding revenue and "complaints" from a couple of luxury clients about Leung's knowledge of the mainland Chinese social-media scene.
Meanwhile, Hay moved from Chicago to Hong Kong in early July to take over as regional general manager of [email protected] across 12 markets in Asia. That role previously belonged to Crampton, who built the team before being promoted to global MD of the agency's social-media offering in December.
Reporting to Crampton now, in addition Hay is leading two key accounts: the Coca-Cola Company's portfolio of brands in Asia Pacific as well as Diageo globally. Prior to this, Fergus was Ogilvy’s worldwide managing director on the SC Johnson business.
