The press conference was arranged outside because Bettel's office is far too small for the 140 press that were invited. Johnson was booed & heckled when he arrived so he chose not to take part in the press conference. I fail to see what is pathetic about Bettel.
I understand all that and for what it is worth, I think Johnson should have attempted to engage in the press conference; however, I thought that Bettel's response was, let us say, against accepted protocol and unnecessary. Perhaps I should have said that rather than pathetic!
