Newly-merged firm Addleshaw Booth & Co has opened in Leeds and Manchester this week to serve "business right across the North". The merger between Addleshaw Sons & Latham, based in Manchester, and Booth & Co, based in Leeds, officially started on the first of February, forming a 97-partner firm which retains both regional offices. David Tully, formerly Addleshaws senior partner, said: "The merger gives us the strength in depth to service the North in a way no other firm in the North can at present." It will operate in seven practice areas, including corporate finance, banking and financial services, and commercial services. The firm estimates its annual turnover will be £41m. Addleshaw Booth & Co is a member of the Norton Rose M5 Group of independent UK practices.
