Cars burn in Belfast, bricks fly in Southampton – and the ubiquitous cry of ‘civil war’ goes up again | John Harris

For most, what we see in real life is mundane. But those who wish to fan the flames of anti-immigrant feeling share a different image online

It was the summer of 2024 when it all decisively started, with the horrific murders in Southport, countrywide violence and Elon Musk’s observation that a British civil war was somehow “inevitable”. A year later came a hot season of flags on lamp-posts, protests outside hotels used to accommodate asylum seekers, the ubiquitous use of the word “tinderbox” and constant predictions of widespread riots that never actually materialised. Now here we are again, in the aftermath of the awful murder and treatment by the police of Henry Nowak and frightening violence and arson in Belfast, and the civil war predictions seem to be increasing by the hour.

The archive of such material is already bulging. In August 2024, amid the riots, a YouGov poll found that 32% of people thought a UK civil war was either “very” or “somewhat” likely. A year later, Dominic Cummings said the UK was only “random viral posts away from riots and prairie fires getting out of control”. Even Labour’s Lisa Nandy offered the opinion that the north of England was so tense “it could go up in flames”.
