    NEW YORK--(BUSINESS WIRE)--Nov. 8, 2005--Willis Group Holdings
Limited (NYSE: WSH) today announced that two of its shareholders
commenced a secondary offering of 6.1 million shares of common stock.
The offered shares are being sold by Profit Sharing (Overseas),
Limited Partnership, an affiliate of Kohlberg Kravis Roberts & Co.
L.P., and Fisher Capital Corp. L.L.C. Concurrent with the offering,
the Company plans to purchase 1.5 million shares directly from the
selling shareholders in a private transaction at the net price per
share to be received by the selling shareholders in the underwritten
