Spirent PLC announces Director/PDMR Shareholding

Crawley, UK -- (MARKET WIRE) -- December 1, 2005 --SPIRENT PLC - NOTIFICATION OF DEEMED INTERESTS BY DIRECTORS, PERSONS DISCHARGING MANAGERIAL RESPONSIBILITY OR CONNECTED PERSONS

Spirent Sharesave Trust Limited, the trustee for the Spirent Sharesave Trust ("the Trust"), has today transferred 158,286 Ordinary shares in Spirent plc (the "Company") at an option price of 41 pence per share to satisfy the exercise of options under the Company's Savings Related Share Option Scheme. Following this transfer the total number of Ordinary shares held by the Trust is :

3,349,850 (representing 0.3469% of the issued share capital of the Company).

The Company's executive directors are potential beneficiaries of the Trust (together with all other UK employee share option holders) and are, therefore, treated under the Companies Act 1985 as having a deemed interest in the total number of shares held by the Trust. As a result, the directors' deemed interest in the Trust has been reduced by the above number of shares transferred.

For the avoidance of doubt, the Company confirms that this notification does not relate to an actual dealing in securities by the executive directors whose interests in the Company's securities remain unchanged notwithstanding the above events.
