My Lords, I will have to write to the noble Lord about that specific question; I have noted it.
Part of what we are seeing in the rise of self-employment is that the number of people working in their own homes is rising as well; computerisation and all of the information technology developments make that much easier than it was 20 years ago. The noble Lord, Lord Deben, has remarked that inspectors could indeed come around and make sure that they have got their computer screens at the right angle and that they are using the right sort of chair. All of these can indeed be regarded as mild risks to those who are engaged in the activity. Again, however, in the balance between risk and regulation, that seems an acceptable risk to the Government, and one would wish to maintain the degree of independence and autonomy that one could have.
