My hon. Friend raises a very important issue. Like the traditional paper petition system, we need to strike a balance in the e-petition system between allowing people to easily register their support for issues that are important to them while discouraging dishonesty. I have been assured that the Government Digital Service has been constantly monitoring signing patterns to check for fraudulent activity. I am sure she will understand that I cannot comment in more detail on the security measures that are taken, but petitions are subject to checks as part of due diligence.
