Allen & Overy (A&O) has boosted its Paris M&A practice with the hire of a trio of lawyers from US firm Debevoise & Plimpton.

The team, which is led by partner Marc Castagnede and includes senior associates Dan Taieb and Olivier Thebault, joined A&O yesterday (21 March), bringing the total number of partners at the magic circle firm's Paris office to 30 and the number of M&A partners to seven.

Castagnede, who specialises in M&A as well as equity capital markets and private equity, has advised on cross-border acquisitions for General Electric, Pernod Ricard, Rexel, Axa, Newell Rubbermaid and Hasbro.

He formerly worked in the legal department of the International Monetary Fund in Washington, before joining Debevoise & Plimpton in 1995.

Castagnede said: "A&O has a very ambitious project in mind here in Paris, where they want to be one of the top firms. It's an ambitious and challenging goal but I'm excited to help the team achieve it."

The hires come after A&O's Paris corporate head Nicolas Bichot left the firm earlier this year to set up his own corporate and tax boutique.

A&O corporate associates Charles-Noel van den Broek and Mathieu Odet also joined the new boutique – Bichot & Associes – as partners.

Bichot has since been replaced as Paris corporate head by Frederic Moreau.
