Slaughter and May has appointed its first female head of corporate in the final round of management elections.
Corporate partner Frances Murphy takes over from new senior partner Chris Saul as head of the corporate department.
Murphy, who has been at Slaughters since joining as a trainee in 1981, said: "I am delighted. It is a real honour that my partners have chosen me. I will be working closely with Chris and the rest of the management team."
The firm has nominated eight practice stream heads, including four promotions, as well as the final eight members of the partnership board.

The heads of the financing, M&A, competition and tax practices remain unchanged.
