Anheuser-Busch InBev's US president, Dave Peacock, is to stand down and will be replaced by Luiz Edmond, according to a report.

Edmond, a native of Brazil, will combine the US position with his existing role of zone president for North America at the Budweiser brewer, according to Ad Age. Citing an internal memo sent to distributors, the publication said yesterday (23 January) that Peacock will continue to serve in an advisory role. 

His departure as president comes amid a tough time for the US' largest brewer. Figures for 2011 are expected to show that Budweiser has lost its place as the country's second most popular beer to MillerCoors' Coors Light, within a shrinking overall market for mainstream lager brands.

A spokesperson for A-B InBev could not be immediately reached for comment.
