I don’t now why the EU negotiator hasn’t made public the detailed bill the UK will be asked to pay to meet contractual obligations, but I don’t doubt that the figures have been made available to the UK team, even supposing they haven’t already been worked out by the Treasury back-room boys.
The point seems to be that Davies’s team wants to know what they’ll get in return, and the EU team aren’t prepared to negotiate on this until the points of principle have been settled: citizens’ rights; Ireland border; agreed financial reckoning.
It beggars belief that the answer to this conundrum wasn’t well-known even before the referendum was called, it seems pretty obvious to me that these issues would be top of anyone’s list if we were going to leave.
Perhaps those who’ve ached for Brexit didn’t much care what sort of shambles would ensue from leaving, because their own interests wouldn’t be affected. I’d bet a penny in the pound that none of the most ardent Brexiteers in politics have much invested in the United Kingdom or its people. They swim in murkier ponds.
