The British military's Surgeon General has defended the use of anti-malarial drug Lariam, despite evidence of serious side-effects among American service personnel.
Air Marshal Paul Evans, the UK's top defence medical officer, told the BBC there's nothing to suggest the drug is not safe, in a rare interview.
Forces TV's Paula Middlehurst, meanwhile, spoke to Dr Remington Nevin, a former US Army doctor, from Johns Hopkins University in Baltimore.
He has previously described the drug as "neurotoxic" and said there are better and safer options for the military to use, because of the risk of "permanent disability".
