US-based international law firm Simpson Thacher & Bartlett has opened a new office in Brussels, Belgium. It is staffed with six lawyers and will specialise in advising clients on European merger control, competition law and regulatory matters post Brexit.

The new office will complement the firm’s existing European locations and is expected to work closely alongside its broader antitrust and trade regulation practice.

The new Brussels location will be led by Antonio Bavasso, who is currently working at Simpson Thacher & Bartlett’s London office. Bavasso will work alongside Simpson Thacher partner Étienne Renaudeau, who will be based between London and Brussels.

Bavasso recently commented on the launch, explaining that the new Brussels office “is another significant step to complement our existing London practice and serve our clients’ interests in Europe”.

Simpson Thacher & Bartlett is headquartered in New York and employs more than 1,000 lawyers across 11 offices worldwide. The company has five locations across the US with additional offices in São Paulo, London, Beijing, Brussels, Hong Kong and Tokyo.
