London, UK, November 4, 2009 - Willis Group Holdings (NYSE: WSH), the global insurance broker, today announced plans to expand its successful Willis Commercial Network business model for serving independent brokers from its base in the UK to countries around the world.

Members of Willis Networks receive technical and sales training from Willis, as well as strategic marketing, compliance, business development and sales support, along with access to Willis' global placement and industry resources.

We believe that the name we have created for our Networks in the UK will resonate in other markets around the world and have appointed Mark to lead the initial charge into Europe and Latin America. The UK networks remain the jewel in our crown and Phil's experience will help us reach our goals of growing the Willis Commercial Network to 100 members and Willis N2 to 120 members by 2011."
