Peter Oborne (We know Boris Johnson is a liar but Rishi Sunak promised truth and integrity. Where is it?, 23 May) is right that the disease of deceit is wrecking British politics, and the reason for it is Brexit. Even one of its fiercest advocates, Nigel Farage, now accepts that Brexit has been an utter failure, but of course the Tory government, with no other notable achievements to its name, can never admit this. Therefore, it has to lie, pretending away all the problems it has caused, and inventing benefits.
Theresa May was discarded by her party because she wasn’t willing to shamelessly lie about Brexit, and they sought a replacement who was. Boris Johnson’s premiership was hence merely a symptom of the disease, not the cause.
