"missile carrying chemicals did not explode, but it releases chemical gases to the moment. The rocket landed inside a civilian house in the city of #دوما yesterday, where more than 50 civilian victims of chemical weapons and dozens of martyrs fell as a result of the shelling of the city with various types of weaponry."

Location 4: "The Bed": "In summary, observations at the scene of the two locations, together with subsequent analysis, suggest that there is a higher probability that both cylinders were manually placed at those two locations rather than being dropped." (Assessment 33)

Now we come to the essential Mr Ian Henderson. Mr Henderson was in charge of the engineering sub-group of the OPCW Fact Finding Mission. The engineers assessed that the story of the cylinders being dropped from the sky was improbable, and it was much more probable that they had simply been placed there manually. There are two major reasons they came to this conclusion.

At least one of the crater holes showed damage that indicated it had been caused by an explosive, not by the alleged blunt impact. The cylinders simply did not show enough damage to have come through the reinforced concrete slabs and particularly the damage which would have been caused by the rebar. Rebar is actually thicker steel than a gas cylinder and would have caused major deformation.

Yet – and this is why Ian Henderson is more important to your understanding of the world than Theresa May – the OPCW Fact Finding Mission reflected in their final report none of the findings of their own sub-group of university based engineers from two European universities, but instead produced something that is very close to the amateur propaganda “analysis” put out by Bellingcat. The implications of this fraud are mind-blowing.

The genuine experts’ findings were completely suppressed until they were leaked last week. And still then, this leak – which has the most profound ramifications – has in itself been almost completely suppressed by the mainstream media, except for those marginalised outliers who still manage to get a platform, Robert Fisk and Peter Hitchens (a tiny platform in the case of Fisk).

Consider what this tells us. A fake chemical attack incident was used to justify military aggression against Syria by the USA, UK and France. The entire western mainstream media promoted the anti-Syrian and anti-Russian narrative to justify that attack. The supposedly neutral international watchdog, the OPCW, was manipulated by the NATO powers to produce a highly biased report that omits the findings of its own engineers. Which can only call into doubt the neutrality and reliability of the OPCW in its findings on the Skripals too.

There has been virtually no media reporting of the scandalous cover-up. This really does tell you a very great deal more about how the Western world works than the vicissitudes of the ludicrously over-promoted Theresa May and her tears of self pity.

Still more revealing is the reaction from the OPCW – which rather than acknowledge there is a major problem with the conclusions of its Douma report, has started a witch hunt for the whistleblower who leaked the Henderson report.

The Russian government claimed to have intelligence that indicated it was MI6 behind the faking of the Douma chemical attack. I have no means of knowing the truth of that, and am always sceptical of claims by all governments on intelligence matters, after a career observing government disinformation techniques from the inside. But the MI6 claim is consistent with the involvement of the MI6 originated White Helmets in this scam. and MI6 can always depend on their house journal The Guardian to push their narrative, as Guardian Middle East editor Brian Whitaker does here in an article “justifying” the omission of the Henderson report by the OPCW. Whitaker argues that Henderson’s engineers had a minority view. Interestingly Whitaker’s article is not from the Guardian itself, which prefers to keep all news of the Henderson report from the public.

But Whitaker’s thesis cannot stand. On one level, of course we know that Henderson’s expert opinion did not prevail at the OPCW. Henderson and the truth lost out in the politicking. But at the very least, it would be essential for the OPCW report to reflect and note the strong contrary view among its experts, and the suppression of this essential information cannot possibly be justified. Whitaker’s attempt to do so is a disgrace.

Which leads me on to the Skripals.

I have noted before the news management technique of the security services, leaking out key facts in a managed way over long periods so as not to shock what public belief there is in the official Skripal story. Thus nine months passed before it was admitted that the first person who “coincidentally” came across the ill Skripals on the park bench, just happened to be the Chief Nurse of the British Army.

The inquest into the unfortunate Dawn Sturgess has now been postponed four times. The security services have now admitted – once again through the Guardian – that even if “Boshirov and Petrov” poisoned the Skripals, they cannot have been also responsible for the poisoning of Dawn Sturgess. This because the charity bin in which the perfume bottle was allegedly found is emptied regularly so the bottle could not have lain there for 16 weeks undiscovered, and because the package was sealed so could not have been used on the Skripals’ doorknob.

This Guardian article is bylined by the security services’ pet outlet, Luke Harding, and one other. The admissions are packaged in a bombastic sandwich about Russian GRU agents.

Every single one of these points – that “Boshirov and Petrov” have never been charged with the manslaughter of Sturgess, that the bottle was sealed so could not have been used at the Skripals’ house, and that it cannot have been in the charity bin that long – are points that I have repeatedly made, and for which I have suffered massive abuse, including – indeed primarily – from dozens of mainstream media journalists. Making precisely these points has seen me labelled as a mentally ill conspiracy theorist or paid Russian agent. Just like the Douma fabrication, it turns out there was indeed every reason to doubt, and now, beneath a veneer of anti-Russian nonsense, these facts are quietly admitted by anonymous “sources” to Harding. No wonder poor Dawn Sturgess keeps not getting an inquest.

Which brings us back full circle to the OPCW. In neither its report on the Salisbury poisoning nor its report on the Amesbury poisoning did the OPCW ever use the word Novichok. As an FCO source explained to me, the expert scientists in OPCW were desperate to signal that the Salisbury sample had not been for days on a doorknob collecting atmospheric dust, rain and material from hands and gloves, but all the politics of the OPCW leadership would allow them to slip in was the phrase “almost complete absence of impurities” as a clue – which the British government then spun as meaning “military grade” when it actually meant “not from a doorknob”.

Now we have seen irrefutable evidence of poor Ian Henderson in exactly the same position with the OPCW of having the actual scientific analysis blocked out of the official findings. That is extremely strong added evidence that my source was indeed telling the truth about the earlier suppression of the scientific evidence in the Skripal case.

Even the biased OPCW could not give any evidence of the Amesbury and Salisbury poisons being linked, concluding:

“Due to the unknown storage conditions of the small bottle found in the house of Mr Rowley and the fact that the environmental samples analysed in relation to the poisoning of Sergei and Yulia Skripal and Mr Nicholas Bailey were exposed to the environment and moisture, the impurity profiles of the samples available to the OPCW do not make it possible to draw conclusions as to whether the samples are from the same synthesis batch"

Which is strange, as the first sample had an “almost complete absence of impurities” and the second was straight out of the bottle. In fact beneath the doublespeak the OPCW are saying there is no evidence the two attacks were from the same source. Full stop.

I suppose I should now have reached the stage where nothing will shock me, but as a textbook example of the big lie technique, this BBC article is the BBC’s take on the report I just quoted – which remember does not even use the word Novichok.

When it comes to government narrative and the mainstream media, mass purveyor of fake news, scepticism is your friend. Remembering that is much more important to your life than the question of which Tory frontman is in No. 10.
