Dozens of billions I agree with. But isn't £12 billion just the accepted EU membership cost after rebates that we continue to pay while we negotiate our leaving the EU? This 'Brexit divorce' bill of €100 billion (£84 billion) confuses me. As far as I understand this is to cover commitment costs to the year 2020. £84 billion over that period is £24 billion yes? How does this square with the £12 billion annual cost of EU membership after rebates? Does this then mean that the £24 billion a year Brexit divorce bill consists of the 'known' £12 billion membership commitments and then £12 billion 'hidden' costs or is it the £12 billion known membership fee plus hidden costs of a £24 billion divorce bill? If it is indeed a punitive financial slap for leaving, does this not make the inherent attitudes of the EU powers that be somewhat akin to a cult like Scientology?
