What happened

Sir Ken McCallum, director general of Britain’s MI5, said in his annual threat update at Thames House on Tuesday that Iran and Russia are escalating hybrid campaigns in the United Kingdom. He said Iran has ramped up attempts to hit British military installations, intelligence facilities and high-security targets, with a suspected plot last month to attack a U.S.-run air base part of that broader effort, and British authorities are investigating a terrorism incident at RAF Fairford. McCallum called Russia “aggressor number one,” said Iran was “subcontracting its UK violence,” and described Iran-led attacks on Jewish communities as “sickening”; intelligence services also warned of a “major shift” in Iranian strategy. The secretary of Iran’s top security body demanded evidence from Britain over the alleged plot against RAF Fairford.
Sourcing check · Fully on the record · 9 articles

8 of 8 articles cite a named source for the story. It was on the record from the first report. Iran’s Ministry of Foreign Affairs denied part of it on the record.

What these terms mean and how they're counted
On the record · names a source 8 of 8
On the record means the article cites a source by name for the story's main claim: a person, or an institution speaking officially, such as a company statement or a named agency's spokesperson. The opposite is an unnamed source. The count is how many of the counted articles cite at least one such source; the names are everyone named across them, each once however the articles spell it. Here: Andy Burnham, MI5 Chief, MI5, President Donald Trump, Ken McCallum and Joint statement by US, UK and 30 other countries
Primary evidence · cites a document or data 0 of 8
Primary evidence means the article cites a record you could check yourself: a court filing or ruling, a dataset or report, a recording or transcript, an official statement or press release, market data. A quote is not a document. The count is how many articles cite one. Here: None cited.
Credits another outlet 0 of 8
The article says the story comes from another outlet's reporting (“first reported by Reuters”). Those articles relay the story; they are not independent confirmation. Here: Each article presents its own reporting.
Unnamed sources 1 of 8
The main claim is attributed to people who are not identified: “people familiar with the matter”, “officials said”. The count is how many articles do this.
On-record denial 1
A named person or institution says the claim, or part of it, is not true. It is on the record — someone signed their name to it — but it is not confirmation, so it never counts toward On the record. Criticizing or dissenting from a decision is not a denial. The count is how many people or institutions deny it; each is listed with the first article that carried the denial. Here: Iran’s Ministry of Foreign Affairs (Daily Caller, Oct 13, 10:41 UTC)
How it developed
When the first report landed and whether it named anyone; when the first named source and the first document appeared. Here: First report Oct 12, 12:26 UTC by Daily Wire, naming its source.
Not counted 1
Opinion, analysis and video pieces, and articles too short to assess. Every count above is out of the counted articles. An article republished under a new headline is one article.
This is about who is cited, not whether the story is true. Each source below says what it names. How we count

Unpacked

Left-leaning coverage never reports the MI5 chief's account of Iran outsourcing attacks inside Britain, the tactical change that right-leaning coverage treats as the heart of the warning. The Washington Examiner says Iran has moved toward "subcontracting its UK violence" after first ranking Russia as the leading aggressor. The New York Times instead treats Tehran and Moscow as both escalating hybrid campaigns and flags attacks on Jewish communities, with no mention of that outsourcing or of any shift in method. Right-leaning coverage leads with the RAF Fairford investigation and a warning about military sites, while the New York Times pairs Iran and Russia and quotes the chief calling attacks on Jewish communities "sickening." What evidence has Britain made public that Iran directed the air-base plot?
Bottom line

A New York Times reader never hears MI5 say Iran is subcontracting violence in Britain. That method, and Russia as aggressor number one, is how the Washington Examiner rendered the same briefing.

The receipts — 3 facts one side's coverage lacks
  • MI5 said Russia remains aggressor number one official statementin Washington Examiner · absent from left-leaning coverage
  • MI5 cited threats to British intelligence facilities and high-security targets official statementin The Hill · absent from right-leaning coverage
  • Headline frames US and allies as recognizing a growing IRGC hybrid-activities threat contextin Washington Examiner · absent from left-leaning coverage
The Left View
Left-leaning coverage treated the briefing as an accusation that Tehran and Moscow are intensifying hybrid operations on British soil, foregrounding McCallum’s characterization of Iran-led attacks on Jewish communities as “sickening” and presenting the suspected air-base plot as one element of a wider Iranian campaign against military and intelligence sites.
The Right View
Right-leaning coverage cast the same remarks as evidence of a “major shift” in Iranian strategy and of allied recognition of IRGC “hybrid activities,” stressing McCallum’s claim that Iran is “subcontracting its UK violence” and tying that warning to the RAF Fairford investigation after he had identified Russia as “aggressor number one.”
Our Take (balanced)
The left’s strongest argument is that McCallum’s pairing of Iran and Russia, plus his “sickening” description of attacks on Jewish communities, shows a multi-state hybrid campaign already unfolding in the UK rather than isolated plots. The right’s strongest argument is that the “major shift,” “subcontracting,” and Fairford investigation language shows the IRGC moving toward contracted violence against Western military sites. The central unresolved tension is whether those warnings and the Fairford incident constitute demonstrated Iranian state-directed attacks, as MI5 presents them, or unproven allegations, as Tehran’s demand for evidence maintains.
