That is another disturbing aspect of the code of practice. In Nottinghamshire, particularly in Mansfield, demonstrations take place in which, generally speaking, the miners form the bulk of those participating. The chief constable has a damned cheek asking for information so that he can decide whether or not the NUM branches in Nottinghamshire can parade their banners. We know only too well that over the years the miners have demonstrated in a proper and peaceful manner. Indeed, I and some of my hon. Friends have been proud to take part in those demonstrations. Things are coming to a pretty pass when it is suggested that they must now give advance information about pit banners.
