A leading expert calls for the NHS to register everyone who has been fitted with hernia mesh and publish complication rates after the programme revealed that up to 170,000 patients in England could be affected by complications. For the first time since two Girl Guide leaders were expelled from the organisation after they criticised its policy on including children who were born as boys but identify as girls, the programme talks to a transgender girl and her mum about her experience in the Brownies. And the programme speaks to the online investigative group who says one of the men suspected of carrying out the Salisbury nerve agent attack is a highly decorated Russian military colonel.
