                         CHAIRMAN'S 2004 AGM STATEMENT





At the Annual General Meeting of Spirent plc (LSE: SPT; NYSE: SPM), a leading
communications technology company, held today John Weston, Chairman, made the
following statement:



"Spirent's overall trading performance in the first quarter of 2004 was in line
with expectations after allowing for the impact of the continuing weakness of
the US dollar to sterling exchange rate.  On an organic, constant currency basis
group turnover was up 9 per cent compared with the first quarter of last year.



"In the Communications group we have started to see some more encouraging trends
in spending by our customers.  The Performance Analysis division has benefited
from our broad portfolio of products, particularly in next-generation broadband
and wireless technologies, with quarterly order intake up appreciably over the
same period last year.  We have also seen some signs of a return of confidence
among network service providers but as previously stated we expect the Service
Assurance division's performance to lag a recovery.  We continue to extend our
existing capabilities in IP services and expand our product offering
internationally.



"Our Network Products group delivered a good performance in the first quarter
benefiting from the introduction of new products and applications in its
principal markets.  As anticipated our Systems group's exports in the first
quarter of 2004 have been impacted by the weakness of the US dollar.



"The satisfactory start to 2004 we reported in our 2003 preliminary results
announcement in February has continued into April.  While we have seen
indications of a pick up in spending by our customers, we continue to be
cautious as to the extent of this recovery."
