::But are the sources in question are "weblogs and advocacy websites"? (1) Martin Bright's "blog". Yes, this is technically a blog, but it is hosted by a reputable newspaper, The New Statesman, of which Bright is an editor, not a personal anonymous weblog. I think its status is no different from an opinion piece in the New Statesman, and thus subject to the same rules, as per WP:RS: "Opinion pieces are only reliable for statements as to the opinion of their authors, not for statements of fact, and should be attributed in-text." In other words, Bright's piece, attributed in text, is a good source for criticism of Press TV, even if not a good source for a fact about Press TV. (2) The Jewish Chronicle: again, a grey area as a RS for a fact, but as good a source as Nick Cohen for the existence of criticism of Press TV. (3) Searchlight (magazine) is not an "advocacy website". It is a magazine with a wide circulation published for some 30+ years, which regularly works closely with mainstream media teams like the Panorama documentary producers.
