City firms Charles Russell and Compton Carr are to merge on 1 May, in a move described as “strategically driven”. The Compton Carr specialisations of media and entertainment, medical negligence and commercial property law will combine with the practice groups at Charles Russell. Leading entertainment lawyer Brian Carr, who joins the firm as a partner, will take a leading role in developing the multi-media department. Richard Vallance, a specialist in medical negligence, and Nigel Richards, a specialist in commercial property law, also join the firm as partners. Senior partner John South said the firm's medium-term priority is to become one of the leading law firms in the evolving 'new media' industries. The merged 45-partner practice will be known as Charles Russell.
