My right hon. Friend raises two important points. Yes, the intelligence agencies are capable of making those changes. They have done a thorough review themselves and, as David Anderson has said, they have released information to him and been candid in their approach. They have shown themselves to be willing to embark on the changes that are needed. We all want to ensure that the recommendations are implemented, and I am pleased to say that David Anderson has agreed to participate in that. We will ensure that the review continues with external assurance from him. I also hope that my right hon. Friend’s Committee will play a role in ensuring that that implementation takes place.
