Will the Prime Minister pass on our best wishes to those who were injured in this morning's outrage? Does he realise that the whole House and, I believe, the whole nation will back him in his determination to ensure that government continues as usual, despite this morning's outrage? Does he agree that the operation of an open democracy necessarily carries with it some risks and that the proper response to terrorism is to do as he has done and make it clear that we will not be deflected in our policies or weakened in our determination to preserve the open and accessible character of our democracy?
