Completely agree with the rest of your post. My question was for those who appeared to be blaming the ambassador for a lack of discretion while seemingly supportive of Trump.None of those questions are relevant. .
I absolutely agree. You make a good point about public interest (which most commentators seem to treat almost like a given - that publishing this material *is* in the public interest.)Other things might be in the public interest. This leak, which has cost a UK Ambassador his job gets a bit close to a great area. Diplomatic communications ought to be protected, they're not in themselves political but are the communications of a civil servant expressing quite frank opinions and providing useful information. This isn't some evidence of corruption or wrongdoing leaked by a whistleblower, it is interesting to read the views but they're not really (IMHO) in the public interests. UK ambassador has sane assessment of trump... well no ****, you'd probably find plenty of other ambassadors; European, Australian, Canadian, NZ have very similar opinions too.
Another consideration is where should protection of the media kick in? The Mail and Oakeshott are both heavily involved actors in Brexit whose interests have been significantly furthered by their scoop. Is it right that they should be awarded some sort of immunity?
