Response to Macquarie's extension of its offer and level of acceptances


The Board of London Stock Exchange plc notes today's announcement by Macquarie
that it is extending the deadline for its offer of 580 pence per share in cash.
Macquarie has received valid acceptances in respect of only 0.4 per cent of the
Exchange's shares.

The Board remains confident of delivering an excellent outcome for the current
financial year and continued strong trading should keep the Exchange on course
to deliver a very strong performance in financial year 2007.  The Board
continues to recommend strongly that shareholders reject Macquarie's offer.
