Amid the election fever I feel it is still important to draw attention to this cardiologist for whom I’ve long had respect. Although I’ve never met him (probably fortunately!) I’m even more delighted that he was based at what used to be my local hospital, the Lister Hospital, Stevenage. For me he is spot on. I cannot understand why he never seems to be on the BBC. So don’t let anyone tell you the sugar tax is a stupid idea.
