There was almost jubilation among Brexiteers when the divorce bill was declared at somewhere between £35 - £39 billion as if it was a small price to pay. They at first claimed we shouldn't pay a penny but then claimed £39 billion was a good deal because the EU had demanded 100 billion Euro. Of course they never demanded any specific figure, other than we should pay what we owe - which we have now done.
This is quite normal for governments. Bad news is almost always dripped out slowly over a long period as if giving it to us in one lot might prove too much for some sensitive souls who would be so shocked they might need medical treatment.
Expect the figure to get higher and higher as time goes on.
