This morning I was already recording some close-up clips of flags fluttering in the sunshine (for use in other videos) when the Brexiter started shouting. He then recognised the elderly former Conservative MP John Gummer and started ranting at him – until a passerby intervened…..

It’s only a short clip and at the time I was so wrapped up in the comical Brexit supporter. But since when did shouting at frail old men belong in British politics?
