Could I give my hon. Friend an example? The phrase that my hon. Friend wishes to replace is more dangerous than it might seem at first glance. The Nottinghamshire miners' rally is held in Bury hill park, a beautiful place. Let us suppose it were argued that photographs were being taken for a memorial edition for the Nottinghamshire miners at some future date. The demonstration sets off from Chesterfield road right up to Bury hill. Let us suppose also that people were taking photographs inside, because this is one of the greatest demonstrations, and it is free, so that any member of the public can attend. If the Nottinghamshire NUM or someone acting on its behalf decided to do a first-class job of taking photographs at the demonstration, that could be regarded as plying for trade or business and be subject to a fine of up to £200, which is just about equal to the cost of the average prosecution under the Health and Safety at Work etc. Act. That is an unfortunate effect of the amendment.
