EXHIBIT INDEX Exhibit No. Description ----------- ----------- 99.1 Press Release of WGHL dated March 13, 2007

                                                                    Exhibit 99.1

              Willis Group Holdings Limited Announces Accelerated
                Share Repurchase of $50 Million of Common Shares

     NEW YORK--(BUSINESS WIRE)--March 13, 2007--Willis Group Holdings Limited
(NYSE: WSH), the global insurance broker, today announced that it has entered
into an agreement to purchase approximately 1.25 million shares of its common
stock from Keefe, Bruyette & Woods using an accelerated stock repurchase program
for an initial purchase price of approximately $50 million. This repurchase is
part of Willis' previously announced stock repurchase program.

     "We believe that the best use of our capital is to continue to buy back our
own stock," said Joe Plumeri, Chairman and Chief Executive Officer of Willis.
"Our strong financial performance, cash flow and balance sheet allow us the
financial flexibility to continue to return value to our shareholders."

     Under the terms of the arrangement, the repurchased shares are subject to a
price adjustment based on the volume weighted average market price of Willis'
common shares during the term of the program. The Company expects the program to
be completed in the first quarter of 2007. All of the shares repurchased under
the agreement will be retired.

     Including this transaction, the Company would have $739 million of
authorized share repurchases remaining under its existing buyback authorization.

     This press release may contain certain statements relating to future
results, which are forward-looking statements as that term is defined in the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements are subject to certain risks and uncertainties that could cause
actual results to differ materially from historical results or those
anticipated, depending on a variety of factors such as general economic
conditions in different countries around the world, fluctuations in global
equity and fixed income markets, changes in premium rates, the competitive
environment and the actual cost of resolution of contingent liabilities. Further
information concerning the Company and its business, including factors that
potentially could materially affect the Company's financial results are
contained in the Company's filings with the Securities and Exchange Commission.
