Should the NHS give priority to certain treatments over others?

Who do you think has a greater right to scarce NHS resources: a smoker addicted to nicotine, or a couple who desperately want a baby but can't conceive without medical intervention?

Stephen got the views of journalist Julia Hartley-Brewer and commentator Dave Atherton.
