On 4 June 2007 London Stock Exchange Group plc was notified that on 31 May 2007
in respect of William Barkshire and 1 June 2007 in respect of John Wallace,
Halifax EES Trustees International Limited, the trustee of the London Stock
Exchange Employee Benefit Trust, purchased 5,663 ordinary shares of 6 79/86
pence each in the Company (Shares) on behalf of the senior executives noted
below who are participating in the London Stock Exchange Long Term Incentive
Plan 2004 (the LTIP) whereby an employee undertakes to use a percentage of their
bonus to purchase Shares in the Company (Investment Shares) and, in return, are
granted a matching award of Shares.

In return for the senior executives purchasing Investment Shares the Company has
granted them matching awards over such number of Shares that equals two times
the number of Shares that the director and senior executives could have bought
had the investment of his or her bonus been made on a pre-tax basis (the
Matching Award).

The following senior executives (being persons discharging managerial
responsibilities) acquired interests in Shares under the LTIP as follows:
Director/PDMR     Number and percentage of Number of Shares         Total beneficial holding of
                  issued class of          conditionally awarded    Shares and total percentage

To be eligible to receive the Matching Award, senior executives must leave their
Investment Shares in the trust and remain in employment for a period of three
years from the date of grant of the Matching Award. The actual number of Shares
transferred to a senior executive on the vesting of the Matching Award will
depend on the extent to which a corporate performance target (which relates to
the Company's Total Shareholder Return relative to a group of comparator
companies) is satisfied over the three-year vesting period.

Full details of the LTIP are provided in the report on directors' remuneration
in the London Stock Exchange Group plc 2006 Annual Report.

This notification relates to a disclosure made in accordance with Disclosure
Rule 3.1.4R(1)(a).
