While associating myself and my hon. Friends on this side of the House with the Prime Minister's expressions of horror at this dastardly and inexcusable outrage, and also with the words of sympathy he has expressed towards the relatives of those who lost their lives, I would like to put one question to him. I quite understand that the right hon. Gentleman may not be able to give details, but we would like to be assured that the Government intend to take every step in their power here, and to provide the local authorities with any sanction they may need to take any steps in their power, to prevent, if possible, a recurrence of any such incident as this.
