Nasdaq Investment in London Stock Exchange plc

The Board of London Stock Exchange plc ("the Exchange") notes Nasdaq's recent
investment in the Exchange at 1,175 pence per share.

The Exchange has extremely strong growth prospects as a standalone business,
reflecting a structural shift in trading patterns facilitated by its Technology
Road Map upgrade, which continues to produce record levels of trading on SETS.
Between January and March 2006, the average daily number of SETS trades grew 38
per cent year on year, well ahead of the rate required to meet the growth
targets set out in the Exchange's shareholder circular of 17 February 2006.
March itself was the third successive record month for SETS, with value traded
up 69 per cent on March 2005.

Furthermore, the Board is exploring the options available to it to create
additional value for shareholders and customers, including discussions with
other major exchanges.  The Board believes that the current share price does not
fully reflect the shift in its growth prospects, its unique franchise or the
strategic options available to it.

The Exchange will proceed with its £510m return of capital.
