Data Retention and Investigatory Powers Bill

My right hon. Friend is absolutely right. People often argue, “Actually, all you need to do is retain data from the point when you’ve identified a suspect or that a crime has taken place,” but when somebody has been murdered, for example, it may be necessary to go back and identify calls between the victim and a number of people. That is why it is important to be able to retain data from the past, but that is for a limited period. Previously, under the regulations that were agreed by this House, 12 months was the set period for retention. One issue that the European Court of Justice raised was that there should not just be one period of retention for all types of data. We are addressing that by making it a maximum period of retention, so it would be possible in any notice to a communications service provider to say that a particular type of data is required to be retained for a period of less than 12 months. We are, therefore, introducing the flexibility that the ECJ required.
