In the last 12 months one laptop has been reported stolen from the Leader of the House of Commons Office. The laptop was used to update the office website and did not contain any personal data or other sensitive information. No data have been lost.Errr.. excuse me? You lost a laptop. What;s more a functioning laptop. Of course data have been lost. What you mean is "we didn't lost millions of records of personal infromation like our tithead colleagues in other departments".
What you did lose though was a profile on the laptop that contains login details, cookies, browsing habits, passwords etc etc. If the laptop connected to the GSI then that supposedly non-data could be very useful.
