As a formerly very fat, self-employed jockey and a self-employed white-collar barrister, I fully appreciate the issues concerned. I agree with my right hon. Friend that these are issues we have to address. He will be aware that we are trialling self-employment matters on an ongoing basis with the National Employment Savings Trust and a variety of private sector organisations. We welcome unions and other organisations that wish to be part of that, and it is front and centre of what we are trying to do.
