Peter Martyr is an enthusiast. His drive is formidable. The Norton Rose boss took a declining City firm into new territories, pioneering the Commonwealth path for expansion – something that Herbert Smith, Ashurst, DLA Piper and Gowling WLG followed, with varying degrees of success.

However, the American deal has not set a fire under the combined firm; as a defensive move it’s pretty smart, but a bold step forward it wasn’t. Despite being one of the few firms to execute a transatlantic merger, Norton Rose Fulbright has plateaued.
