Police Reform and Social Responsibility Bill

Perhaps the Leader of the House could help me. From the muttering around the House, it would seem that there is a feeling that perhaps the noble Lord, Lord Harris, should not move his amendment in view of the clear indications given by the clerks. However, I am not clear about what the procedure should be now. Should there be a Motion before the House as to whether the amendment should be moved, on which, if necessary, the House can divide? How does it work? I never came across this particular type of issue when I was Leader of the Opposition or Leader of the House, or since. I should be grateful if the noble Lord could enlighten me.
