While I agree with much of what this article says about May –
as prime minister she has shown that she has a lethal blend of tunnel vision and obstinacy that automatically produces ill-judged decisions – it may be a little early to start talking about legacies.
For starters, it was not May who started this, and she supported and voted Remain. Cameron started this pot boiling with the cooperation of the Tory party in order to keep keep UKIP from undermining the Tory majority – which says a lot about the sort of people who support the Tories. If the Good Friday Accords get shredded or nullified, as they must do in any Brexit worthy of the name, then it’s the legacy of the Tory party and its thrust for power. At least May was aware of the importance of that agreement in her attempt to put in a backstop to keep the border open. In fact, it could ultimately lead to Irish unification, which is one solution to the brexit conundrum.
May is undoubtedly responsible for how she conducted herself as prime minister. On top of a narrow Leave victory in 2016, she made a massive error of judgement in calling an election in 2017, thinking this would ratify the referendum. She lost. Even after that, it didn’t dawn on her that she wasn’t a dictator able to accomplish brexit by fiat. She refused to consult anyone but the Tory right; she ignored nearly half the country that chose to Remain; she refused any compromise with the opposition; and she treated negotiations as if the UK had the upper hand.
She was a fool, but let’s wait to see the scale of her disaster before assigning a legacy.
