Is there any particular reason this link is actually worth reading? Is 'Crag Murray' a former high-level politician/intelligence officer with useful information? Do they have a track record of finding genuine and severe issues with government narratives?
Craig is a former ambassador to Uzbekistan, who served in the Foreign Office for many years. He's since dedicated a lot of his time to following and reporting on the Assange case in the UK.
He doesn't hide his opinions, some of which are quite strongly worded, but I don't think that makes him less worthwhile as an observer. I'd say he is less of a fact-finder/whistleblower and more of an analyser/commenter.
I personally find his articles insightful and nuanced.
