I thank my hon. Friend for the work she did in bringing the Bill through and turning it into an Act. It is an important piece of legislation, which extends our powers to work alongside network providers. We are taking significant steps in dealing with the security threat posed by mobile phones. We have to prevent them from getting into prisons. We have to use detection methods to find them and stop them working, and we are making advances on that. We also need to exploit the data that is held on them.
