Classical scholars must surely see parallels between the embarrassing sequence of prime ministerial changes in the British government this year and events in AD68-69 in the ancient Rome so beloved of Boris Johnson.
AD68-69 was the year of the four emperors. First there was Galba, murdered by soldiers of his Praetorian Guard – this year’s parallel being the removal of Johnson by his long-suffering cabinet. Then there was Otho, who took his own life – this year’s version being the political suicide committed by Liz Truss with her lunatic budget.
