More than a decade after her death and 34 years since she left Downing Street, Margaret Thatcher continues to haunt us. After Liz Truss’s cosplay as the Iron Lady, Rishi Sunak has drawn comparisons between “the grocer’s daughter and the pharmacist’s son”. In December last year, Keir Starmer admiringly said that Thatcher “set loose our natural entrepreneurialism”. All this suggests a very British mixture of muddle and masochism: her spirit, it seems, must be summoned so we can be magicked out of our current mess, even if so many of the UK’s crises began with what she did.
