Think this is the first time I have ever disagreed with you John, if the man was an unknown individual, then you are possibly correct, but as the Leader of Her Majesty's Opposition then he has a duty to show respect to the country he represents, and he does represent it, even as Leader of the Opposition as he will meet other world leaders whilst in that role. If he shows no respect for his own country why should others. Even his own party members have been vociferous in their disappointment in his attitude towards established protocol.
