I recently had the pleasure of discussing the art of messaging with Matthew Ryder QC, an eminent barrister and also London’s Deputy Mayor for Social Integration, Social Mobility and Community Engagement. This is a man who really knows how to communicate with impact, hence a brilliant legal career, followed by a high-profile political appointment. Matthew told me he always reminds junior barristers attending his lectures that “facts are protein, opinions are carbs”. I immediately asked (and received!) his permission to steal this excellent metaphor.
