Penelope Warne is the Senior Partner and Chair of the Board at CMS Cameron McKenna; she is the first woman to hold this post at CMS, the tenth largest global law firm. Penelope studied law at Bristol University and initially worked as a banking lawyer at Slaughter and May before joining CMS in 1993. She established the firm’s Aberdeen office and upon moving to Scotland attained her qualification in Scots law, to add to her existing English qualification. Her achievements in the corporate world are highly significant given that, according to The Lawyer magazine, only 18.6% of partners in the UK’s top 20 law firms are women; though it is noteworthy that CMS fares much better (30% of its salaried partners, and 25% of its equity partners, are women). Penelope is an Honorary Fellow and Trustee of the Centre for Energy, Petroleum and Mineral Law and Policy at Dundee University, and is a member of the Foundation Board at IMD Business School, Lausanne. In early 2015, she was named as one of only 20 people in the law category in The Sunday Times ‘500 Most Influential’. She is committed to gender diversity in the legal profession and wants to use her influence to ensure that a supportive culture is created at CMS ‘embracing all aspects of diversity, so that the careers of all in CMS can thrive’.
