David Cameron has welcomed the Crown Prosecution Service's decision to drop charges against the parents of five-year-old Ashya. Health Secretary Jeremy Hunt told ITV News the Government is offering to fly one of the NHS' top medical experts to Spain to give advice on the next course of action for five-year-old Ashya.
