Dear Sirs

WILLIS GROUP HOLDINGS LIMITED (THE "COMPANY")

    We have acted as Bermuda counsel to the Company, and this opinion as to
Bermuda law is addressed to you in connection with the filing by the Company
with the United States Securities and Exchange Commission under the Securities
Act of 1933, as amended, of a Registration Statement on Form F-1 (Registration
No. 333-87622) and related documents and the Registration Statement on Form F-1
filed pursuant to Rule 462(b) (together, the "Registration Statements") in
relation to the sale by certain shareholders of the Company (the "Shareholders")
of 19,290,000 of the issued common shares of the Company, US$0.000115 par value
per share (the "Shares"), held by them. The underwriters have been granted an
option to purchase up to 2,893,500 additional shares from the Shareholders to
cover over allotments.

    For the purposes of this opinion we have examined and relied upon the
documents listed, and in some cases defined, in the Schedule to this opinion
(the "Documents").

    Unless otherwise defined herein or in the Schedule to this opinion, terms
defined in the Registration Statements have the same meanings when used in this
opinion.

    ASSUMPTIONS

    In stating our opinion we have assumed:

    (a) the authenticity, accuracy and completeness of all Documents submitted
       to us as originals and the conformity to authentic original Documents of
       all Documents submitted to us as certified, conformed, notarised, faxed
       or photostatic copies;

    (b) the genuineness of all signatures on the Documents;

    (c) the authority, capacity and power of each of the persons signing the
       Documents which we have reviewed (other than the Company or its Directors
       or Officers);

    (d) that any statements of fact or law, other than as to Bermuda law, made
       in any of the Documents are true, accurate and complete;

    (e) that the records which were the subject of the Company Search were
       complete and accurate at the time of such search and disclosed all
       information which is material for the purposes of this opinion and such
       information has not since the date of the Company Search been materially
       altered;

    (f) that the records which were the subject of the Litigation Search were
       complete and accurate at the time of such search and disclosed all
       information which is material for the purposes of this opinion and such
       information has not since the date of the Litigation Search been
       materially altered;

                                       7

    (g) that there are no provisions of the laws or regulations of any
       jurisdiction other than Bermuda which would be contravened by the
       transfer of the Shares or which would have any implication in relation to
       the opinion expressed herein and that, in so far as any obligation to be
       performed or action to be taken as described in the Registration
       Statements is required to be performed or taken in any jurisdiction
       outside Bermuda, the performance of such obligation or the taking of such
       action will constitute a valid and binding obligation of each of the
       parties thereto under the laws of that jurisdiction and will not be
       illegal by virtue of the laws of that jurisdiction; and

    (h) that the Resolutions are in full force and effect, have not been
       rescinded, either in whole or in part, and accurately record the
       resolutions passed by the Board of Directors of the Company in a meeting
       which was duly convened and at which a duly constituted quorum was
       present and voting throughout and that there is no matter affecting the
       authority of the Directors not disclosed by the Constitutional Documents,
       the Company Search, the Litigation Search, or the Resolutions, which
       would have any adverse implication in relation to the opinions expressed
       herein.

    OPINION

    Based upon and subject to the foregoing and subject to the reservations set
out below and to any matters not disclosed to us, we are of the opinion that:

    (1) The Company is an exempted company validly organised and existing and in
       good standing under the laws of Bermuda.

    (2) All necessary corporate action required to have been taken by the
       Company in connection with the original issuance by the Company of the
       Shares, and all necessary corporate action required to be taken by the
       Company in connection with the transfer of the Shares by the
       Shareholders, pursuant to Bermuda law, has been taken by or on behalf of
       the Company, and all necessary approvals of Governmental authorities in
       Bermuda were duly obtained for the original issuance by the Company of
       the Shares and have been duly obtained for the transfer by the
       Shareholders of the Shares.

    (3) Based solely upon the entries in the Share Registrar of the Company, the
       shares are validly issued, fully paid and non-assessable shares in the
       capital of the Company.

    (4) There are no taxes, duties or other charges payable to or chargeable by
       the Government of Bermuda, or any authority or agency thereof in respect
       of the transfer of the Shares.

    RESERVATIONS

    We have the following reservations:

    (a) We express no opinion as to any law other than Bermuda law and none of
       the opinions expressed herein relates to compliance with or matters
       governed by the laws of any jurisdiction except Bermuda. This opinion is
       limited to Bermuda law as applied by the courts of Bermuda at the date
       hereof.

    (b) In paragraph (1) above, the term "good standing" means only that the
       Company has received a Certificate of Compliance from the Registrar of
       Companies in Hamilton Bermuda which confirms that the Company has neither
       failed to make any filing with any Bermuda governmental authority nor to
       pay any Bermuda government fee or tax, which might make it liable to be
       struck off the Registrar of Companies and thereby cease to exist under
       the laws of Bermuda.

    (c) Any reference in this opinion to shares being "non-assessable" shall
       mean, in relation to fully paid shares of the Company and subject to any
       contrary provision in any agreement in writing

                                       8

       between such company and the holder of such shares, that no shareholder
       shall be bound by an alteration to the Memorandum of Association or
       Bye-laws of the Company after the date on which he became a shareholder,
       if and so far as the alteration requires him to take, or subscribe for
       additional shares, or in any way increases his liability to contribute to
       the share capital of, or otherwise to pay money to, the Company.

    (d) Searches of the Register of Companies at the office of the Registrar of
       Companies and of the Supreme Court Causes Book at the Registry of the
       Supreme Court are not conclusive and it should be noted that the Register
       of Companies and the Supreme Court Causes Book do not reveal:

        (i) details of matters which have been lodged for filing or registration
            which as a matter of general practice of the Registrar of Companies
            would have or should have been disclosed on the public file but have
            not actually been registered or to the extent that they have been
            registered have not been disclosed or do not appear in the public
            records at the date and time the search is concluded; or

        (ii) details of matters which should have been lodged for registration
             but have not been lodged for registration at the date the search is
             concluded.

    (e) In order to issue this opinion we have carried out the Company Search as
       referred to in the Schedule to this opinion and have not enquired as to
       whether there has been any change since the date of such search.

    (f) In order to issue this opinion we have carried out the Litigation Search
       as referred to in the Schedule to this opinion and have not enquired as
       to whether there has been any change since the date of such search.

    (g) Where an obligation is to be performed in a jurisdiction other than
       Bermuda, the courts of Bermuda may refuse to enforce it to the extent
       that such performance would be illegal under the laws of, or contrary to
       public policy of, such other jurisdiction.

    DISCLOSURE

    This opinion is addressed to you in connection with the filing by the
Company of the Registration Statements with the United States Securities and
Exchange Commission and is not to be made available to, or relied on by any
other person or entity, or for any other purpose, without our prior written
consent.

    This opinion is addressed to you solely for your benefit and is neither to
be transmitted to any other person, nor relied upon by any other person or for
any other purpose nor quoted or referred to in any public document nor filed
with any governmental agency or person, without our prior written consent,
except as may be required by law or regulatory authority. We hereby consent to
the filing of this opinion as Exhibit 5.1 to the Registration Statement on
Form F-1 filed pursuant to Rule 462(b). Further, this opinion speaks as of its
date and is strictly limited to the matters stated herein and we assume no
