A woman from March in Cambridgeshire is calling for a controversial operation designed to cure incontinence after childbirth to be suspended.
The Medicines and Healthcare Products Regulatory Agency says it believes the benefits of the operation outweigh the risks.

The government's healthcare watchdog says it sympathises with women who have suffered complications and it will continue to monitor their safety and performance.
