Stonewall’s annual Workplace Equality Index saw three other firms also retain a position in the top 100 including Pinsent Masons, in 36th place, Herbert Smith, in 56th place, and Eversheds, in 85th place.

The same four firms were represented in last year’s top 100, although all of them have improved their positions. Their respective positions in 2009 were Simmons & Simmons at 31, Pinsent Masons at 50, Herbert Smith at 77 and Eversheds sneaking in at 100.
