Boris Johnson makes so many continuous mistakes – I’m being polite – that his subsequent attempts at revisionism (those re-framing euphemisms, for example, to try and lesson the original disastrous expressions/promises/assurances) are now legendary drivel. This one is simply inaccurate because we know the algorithm was designed to produce the inequalities and injustices it did! Also, the application of the algorithm was employed to prevent teacher assessment being used, this an ideological intervention that had nothing to do with awarding the most accurate assessments in complex times and everything to do with suppressing professional input.
