On 17 September last year, the day before Scotland voted by a 10-point margin to remain part of the UK, I attended the SNP’s final referendum campaign rally at the Concert Hall in Perth. The event began smoothly enough—saltires were unfurled, the PA system played nationalist pop anthems (such things exist, by the way), and activists gradually massed in front of the main stage, waiting for Alex Salmond and Nicola Sturgeon to arrive.
About 25 minutes in, however, the mood suddenly changed. A BBC News team, led by its political editor, Nick Robinson, had appeared in the gallery and a section of the audience had started jeering. SNP officials gestured frantically for the heckling to stop. Moments later, Robinson and his colleagues left.
