My hon. Friend is factually wrong on a number of those points. The budgeted costs certainly have not increased by 300 per cent., as he suggests; there has been a much more limited increase of about £180 million out of the £7.1 billion. I have to say to my hon. Friend that this project is going to save money in comparison with legacy methods of fulfilling the same role. That is very important. Also, it is an absolutely essential part of modern warfare that we should have effective, secure communications, linking all aspects of our armed forces, at home and abroad in theatre. That is part of the network-enabled capability to which we are committed.
