As the Leader of the House has followed with such obvious care the detail of what was said throughout that night of squalor and disgrace last Thursday, will he tell us why he did not at some stage in the proceedings step in to try to prevent what was happening? None of us can believe that he wanted the House to demean itself in such a way. We have been told that the Prime Minister was in favour of the course that was taken, but we cannot believe that the right hon. Gentleman was. Why did he not intervene to stop what was happening when he knew that he had the power to do so?
