The theft of Hazel Blears' personal computer from her constituency has put government data security under the spotlight once again.
Thieves broke in to the constituency office of Hazel Blears, secretary of state for communities and local government, last Saturday afternoon through a window and stole her PC.
In the wake of the incident, the prime minister's spokesman said permanent secretaries should remind staff of the importance of enforcing procedures on the treatment of sensitive information.
The spokesman said it was against the rules to have government information on a personal computer, but said he did not want to speculate on the case until the full facts were established.
Strict procedures were introduced in Whitehall last year to protect data following a series of high profile data losses.
