Exhibit 99.1 Willis Group Holdings Announces Results from Annual Meeting of Stockholders NEW YORK--(BUSINESS WIRE)--April 29, 2005--Joe Plumeri, Chairman and Chief Executive Officer of Willis Group Holdings Limited (NYSE: WSH), the global insurance broker, outlined the Corporation's progress through 2004, reflected on sweeping transformations taking place in the global insurance industry and the Company's platform for growth at the Annual Meeting of Shareholders which was held on April 29, 2005 in New York City. "We celebrated a number of significant accomplishments in 2004 which will have a lasting impact for our shareholders, our clients and Associates around the world," said Mr. Plumeri. "Demonstrating long-term confidence, the Board of Directors increased the dividend to $0.75 per share annually in February 2004 which was subsequently increased to $0.86 per share annually in February 2005.

We strengthened our global footprint by increasing our holding in Willis Denmark to 100% and bought a majority stake in Coyle Hamilton which was the largest, independently owned insurance broker in Ireland. "Insurance is a great and vital industry - but for too long has been inwardly-focused. Accepting and embracing the metamorphosis that has come with the heightened scrutiny of industry accepted conventions, we are leading the efforts of transparency and are further demonstrating our commitment to the tangible, measurable value we deliver to clients," Plumeri continued. "This changing environment brings challenges but many more opportunities which we face with excitement and confidence," Plumeri noted. "We are challenging our own conventions and assumptions in order to reinforce our business around the world and are confident we will emerge with a stronger more resilient model for long-term success."
