asked the Parliamentary Secretary to the Ministry of Food whether, as a result of the "Eat more potatoes" campaign, there has been a noticeable reduction in the consumption of bread?

I regret that the evidence at present available to me does not enable me to answer my hon. Friend with any substantial degree of accuracy, but a recent sample examination of bread sales indicates that a reduction is taking place. Further returns now being collected will, I hope, enable me to give a more precise answer in about three weeks' time.
