My Lords, the noble Lord, Lord Warner, is right that we need to have a trigger mechanism. This is gold-plating, and not very effective gold-plating. As the noble Baroness, Lady Finlay, just said, it will produce an absolute mass of information. The question is how to find, among that mass of information, situations where there is malpractice, abuse or unwarranted price rises. It is the same sort of argument as we had when the police wanted to collect everybody’s internet information. Really, it is like looking for a needle in a haystack. It is much better to have it targeted, where there is a reason to believe that there is something going on.
How will the department identify from this mass of information those situations that it needs to investigate further? Will it apply some sort of algorithm to the information at any point along the production or distribution line when there is an increase of more than a certain percentage or a certain percentage related to the average—or what? How is it going to be done? These companies have quite enough to tackle with Brexit coming along the track and do not need a further burden such as this.
