You make a good point and I retract my previous thought that this matter is not political other than involving political inertia or laziness.
But I do think the Government has an obligation to at least try to sort out deceitful practices in the food industry regardless of its effect upon public expenditure.
Honey is not simply diluted with syrup. It is sometimes not even honey as we define it, having been harvested as nectar and dried artificially. There are also substances that are used with bees in some countries that would not be permitted elsewhere. There are records of honey having had added to it a chemical compound that is also used in suncream. Under analysis its presence simulates the chemical formulation of manuka honey, and in general, the more concentrated the amount of that chemical, the more valuable the honey. So there are some actual health concerns.
I am being cynical in stating that the Government does not consider there to be an issue with adulterated honey.....I assume that to be just what it wants us to believe.
