I find myself in sympathy with both sides of the argument; I very much see the point my hon. Friend is making, but I also sympathise with the concerns expressed by my hon. Friend Robert Halfon. Will my hon. Friend consider some sort of sunset clause that would allow Parliament, after a period of time, to reflect on how well the changes have operated so that, if some of the concerns that have been raised appear to have been justified, we might consider changing once again?
