Speaking in the Commons, Home Office minister Nick Hurd said the cases of Billy Caldwell and Alfie Dingley had "highlighted the need for the Government to explore the issue further and our handling of these issues further". Mr Hurd told MPs he has asked chief medical officer Dame Sally Davies to begin work on the panel. It comes after the mother of 12-year-old Billy, who has acute epilepsy, demanded a meeting with home secretary Sajid Javid and health secretary Jeremy Hunt within 24 hours. Charlotte Caldwell had cannabis oil used to treat her son's condition confiscated from her at Heathrow airport earlier this month.
