asked the Chancellor of the Exchequer what is the amount of the Import Duty on nicotine used as an insecticide by hop-growers, farmers, and gardeners; and whether he can give any reason for nicotine being much more expensive to users of that insecticide in this country than in France?

There is no Import Duty on nicotine, nor is there any duty upon nicotine manufactured in this country. With regard to the last part of the question I have no information.
