Boris Johnson’s prime ministerial innings in the UK has had so many twists that it has begun to seem as if the action is staged, a trial script for a Netflix political drama perhaps, rather than the narrative of a government and a country in decline. A few months ago, there was a bruising inquiry that showed the prime minister had attended a party of staffers while the UK was in lockdown and allegedly misled parliament about it. June saw a Commonwealth summit in Rwanda; what would ordinarily be an uplifting bit of historical theatre instead refocused criticism on the UK government’s bizarrely inhuman plan announced this year to transport illegal immigrants to Rwanda.
