Mr. Chris Macey:

There is a lot of research around and many examples of taxes being imposed, though less on subsidies. South Africa and India are two examples where subsidies on healthy products like fruit and vegetables have worked very well. The research that is out there says it works and where the two are combined it is bound to magnify. If we are spending the proceeds of the tax on helping the children who need help most, then we will magnify the impact of the tax, which is significant anyway, according to the UK figures.
