BERLIN—Brussels-based public affairs consultancy Interel has concluded an asset transfer deal that creates a formal partnership with Berlin-based government relations firm Bohnen Kallmorgen & Partner.

The move boosts Interel’s German presence to 10 full time consultants supported by a senior advisory board of former policy makers and diplomats. The Interel BKP partnership also includes a joint office and the ability to seamlessly share resources and capabilities for the benefit of the two firms growing client list.

BKP co-founder Jan-Friedrich Kallmorgen—who previously worked with Goldman Sachs and the German Council on Foreign Relations—will join Interel as a partner together with a team of four staff and a portfolio of clients. Markus Weilding, who joined Interel in mid-2013 from the DAPD News Agency, will be managing director of the combined operation, while Claudia Conrad Kreml has been named chairman and will continue to advise clients.

According to Interel Group CEO, Fredrik Lofthagen: “Germany is of huge importance as an economic power house. It’s a business destination in itself and route to all major markets worldwide. Strengthening our German office is a key part of our growth strategy.”

In addition to Brussels and Berlin, Interel has offices in Paris, London, and Washington, DC, and a network of international partners that allows it to deliver cross-border public affairs advice.
