Bird & Bird has beaten off competition from five other firms to retain its £1m post as legal adviser to the Government's Central Computer and Telecommunications Agency (CCTA).
The firm has held the post since 1994 but earlier this year, as part of the agency's competitive retendering exercise, five other practices were asked to make presentations to win the next five-year contract.
Roger Bickerstaff, a partner at Bird & Bird, said the work involves providing specialist computer law advice on systems acquisitions and on PFI projects at the CCTA's headquarters in Norwich. It has also given direct support on specific projects around the country.
In addition, the firm gives preliminary advice on disputes with systems suppliers. However, any litigation is handed over to the Treasury Solicitor's Department.
Three solicitors from Bird & Bird have been seconded to the CCTA on a part-time basis, including Bickerstaff, who is currently head of the CCTA's legal and commercial practice. He said he would remain head for a minimum of two years.
Commenting on the firm's reappointment, Bickerstaff said: "We are delighted that our hard work over the past four years has been recognised... Repeat business is always the best business."
