My hon. Friend has been a stalwart campaigner on this issue, which, as he rightly points out, is of great interest to Members on both sides of the House and to the Select Committee. He will be aware that we undertook a consultation earlier this year, and we are reviewing the responses. He is also right to highlight the important contribution that organisations such as the Federation of Small Businesses have been able to make in putting forward further research reports. We hope to be able to publish that kind of information very shortly so that more people will be able to look at the responses.
