With regard to the question of interference there is an advisory committee dealing with this matter. The Minister has power to prosecute, if necessary, if interference is caused but so far the Authority has not recommended prosecution in any case. They prefer to get co-operation which, up to now, they have been getting quite freely. We are trying to insist that all electric motors and ignition apparatus should not cause interference. When they are turned out new at the present time they are all fitted with the necessary suppressors. Quite frequently it is our experience that it is not outside interference from engines of mopeds which cause interruption in the service but interference from some of the gadgets, if I may use the word, within the household. People are usually advised to check their own electrical equipment and such things before they make complaints. When I say no prosecutions have been recommended, I want to add that the Minister can prosecute if the Authority so recommends. Due to the fact that sufficient co-operation has been forthcoming at all stages, they have been able to do very useful work so far without prosecution by getting the full co-operation of the owners of those vehicles and devices which are likely to cause interference.
