I thank the hon. Gentleman for his intervention and his compliment that he thinks my point is not wholly without merit, but it might test your patience, Mr Deputy Speaker, if I tried to shoehorn into the debate on the amendment possible solutions to the global food crisis and productivity in agriculture.
On derivatives, in agricultural production there is a need to hedge. There needs to be some kind of financial security to take account of unforeseen weather events and so on, so of course there is a need to hedge, but that is not what I am talking about. The question is whether some of the recent high-volume, high-speed forms of speculation and trading have had an impact on the global food price. I suspect that they might have, but it would be nice to have more information.
