I won't get over-involved in historic situations as I prefer to look forwards, not backwards. But just taking Pierre's first point. Nigel Farage was claiming as recently as 2017 that there would be no divorce bill. We now know that that is false. As an MEP, if he didn't know this then I suspect many others didn't either. And who can forget it taking a Brexit Secretary some two years to understand the importance of the Calais-Dover crossing for UK trade?
