SJ Berwin has launched an office in Luxembourg with the addition of two new partners, including former Allen & Overy (A&O) lawyer Alexandrine Armstrong-Cerfontaine.

The base, which opened today (2 January) will focus on corporate, finance, private equity, funds and tax, and will be led by Armstrong-Cerfontaine, who set up her own Luxembourg firm Armstrong Cerfontaine Avocats in 2009 after leaving A&O.
