Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, how many IT systems which his Department uses are more than (a) three, (b) five and (c) eight years old; and what steps he is taking to ensure that all his Department's IT systems are updated promptly.

Treasury systems are subject to regular patching and version updates in line with recommendations from the National Cyber Security Centre. We currently have one system that is more than three years old and work is ongoing to update this.
