Mr Sullivan, it transpires, is the co-organiser with Mr Smyth of the Trump Arms celebrations.
Thanks to him, Friday’s mainly invitation-only grand opening will, Mr Sullivan says, be attended by Trump supporters and people from “various conservative groups”.
There will be people from the Bow Group, a conservative think tank, and from the Bruges Group, which credits itself with having “spearheaded the intellectual battle to win a vote to leave the European Union”.
