Cooley, Clifford Chance and Latham & Watkins have the highest proportion of black lawyers in the U.K. according to research that lays bare the lack of racial diversity within the profession.

A survey of the 50 largest law firms by International found Cooley topped the table, with five of its 113 U.K. lawyers saying they are black. Other firms that ranked highly were Ashurst, Ropes & Gray, Shoosmiths and Sidley Austin.
