NEW YORK — Edelman Global Advisory Services has expanded its international reach with the purchase of Landmark Public Affairs — EGA’s second acquisition in roughly a month.

The addition of Landmark — which has offices in Brussels, London, Singapore and New York City — will bolster EGA’s expertise in policy and geopolitical issues. Landmark has staff in 20 countries.

Brussels-based Rocco Renaldi, who launched Landmark in 2007, will serve as chair of EGA Europe as well as global chair of food & beverage policy. EGA’s Feargal Purcell and Landmark’s David Bates will serve as co-vice chairmen, EGA Europe; Amaia Betelu will serve as acting president of EGA Brussels.

In addition, Landmark partner Jackie Smith will join EGA as a senior advisor. Richard Andrew, Landmark’s managing director for Asia, will serve as EGA co-chair of Asia Pacific, as will EGA’s Gracie Sun.

Landmark North America managing director Julien Lafleur will serve as managing director of EGA New York, where he and his team will spearhead the expansion of EGA’s global stakeholder engagement.

“EGA’s outstanding growth over the last year is proof that the intersection between business and societal and geopolitical issues has become far more frequent across the globe,” said Edelman CEO Richard Edelman. “Our clients are seeking counsel on how to navigate this complex environment. The acquisition of Landmark deepens our regulatory, policy and advisory capabilities in Europe and Asia.”

The Landmark acquisition comes roughly one month after EGA — an Edelman boutique specializing in government and business advisory —announced its purchase of Brazilian government relations firm Distrito Relações Governamentais.

The addition of Distrito’s networks across Latin America and regulatory insights will strengthen EGA in the fast-growing region, while providing Distrito clients access to EGA experts worldwide, EGA said in announcing the deal.
