I thank the hon. Member for his comments and understanding. He asked about support for the families. The Home Office, along with Thames Valley police, is providing all the necessary support, particularly through family liaison officers but also through the victims of terrorism unit at the Home Office. He referred to one particular agency, but of course many other agencies work across the intelligence and security spectrum. We work with all of them, because they are part of that integrated network along with policing, frontline policing and counter-terrorism policing. That work will continue and, as I have already said to the House, if there are any issues, lessons or lines of inquiry to be followed up which we can proactively address and deal with, either in this House or through my actions as Home Secretary, I will absolutely follow them up.
