I hesitate to give a full answer, but the advice I have received is that over the years these products have been reviewed and there are clinical standards for the size of the mesh. I will write to my hon. Friend in more detail, because I am not an expert in that.
The hon. Member for Kingston upon Hull West and Hessle calls for a public inquiry. I think it is more important that we get the treatment that is needed, but I encourage everybody to report their cases through the yellow card scheme.
I am horrified to hear from my hon. Friend the Member for Totnes that many women did not know they were having the device fitted in the first place. That general issue indicates some arrogance of the medical profession towards women. The stories I have heard from colleagues, about how their constituents have been treated by their GPs when they have gone for treatment, are indicative of that. Women tend to suffer in silence. Quite often that means they are not the best at championing themselves. That is clearly unacceptable. This issue has been considered by the mesh oversight group, and it has been clear that improvements are needed to ensure informed consent.
