U-turns tend to be humiliating events. When performing them in a car, there’s the shame of your GPS incessantly ordering you to turn around amid the angry honking of drivers’ horns; in -government, the shaming is gleefully carried out by the media and the opposition.

Political U-turns are perceived to be so ignominious, in fact, that lawmakers seem to feel the need constantly to insist they are not guilty of them. “You turn if you want to. The lady’s not for turning,” Margaret Thatcher told the Conservative party conference in 1980, seeking to show her strength and mark a conspicuous change from the previous Tory prime minister, Edward Heath, whose reversal on economic policy in the early 1970s had provided the original impetus for the metaphor.

We have certainly seen our fair share of government U-turns during this pandemic. In Britain, the most notable recent one was the decision to extend the provision of free meals to underprivileged children to cover the school summer holidays, after pressure from a campaign led by footballer Marcus Rashford. According to Hansard, the term was used in Parliament more often in June 2020 than in any other month ever, with the two dreaded syllables uttered a total of 69 times.
