And why I mention it: Boris Johnson is turning the Rule Britannia affair into a Trump-style culture war – and the BBC is letting him get away with it.

Was actually at the Last Night of the Proms in 1973. A peak moment of my life and remember it better than yesterday. Every country has a glorious past and has a right to recall its sweetness. In Australia, of course, that moment is the bodyline test, and for Canada it’s the eighth game of the Canada-Russia series in 1972. But for myself, Canadian-born as I am, I have always shared Britain’s triumphs as part of my own personal heritage.
