What does Skripal know?

Whatever he knows is enough for his own life and those of his family to be put under threat.

Why does The Sun want his wife and son killed in car crashes, when the deaths were reported elsewhere as occurring otherwise?

See the difference between Sputniknews and The Sun, for example.

Sputniknews. Following the incident, several media reports indicated that the UK police was carrying out the exhumation of bodies as part of a probe into the poisoning of Skripal. His wife died of cancer in 2012, while his son died from liver failure in 2017 and was buried in the United Kingdom.  www.sputniknews.com

The Sun.  It is the latest tragedy to befall his young family after both his wife and son died in mysterious car crashes. Here’s what we know…   https://www.thesun.co.uk/news/5744389/sergei-skripal-wife-son-cause-death-car-crash-disseminated-endometrial-carcinoma/

The only certain conclusion to draw about this case is that you cannot believe even one word that is appearing in the media.   All the incidents occurred in the South West of England.  Was Skripal in some way penetrating Porton Down, and had knowledge about British dirty tricks in Syria – say?  If the truth is going to be found, we won’t find it in any mainstream sources.  That’s for sure.  All we’ll get is more smokescreen hiding whatever it is, which clearly worries Theresa May and others in government.

It’s easier to work from what we might know from the earlier assassination of former Russian FSB member Alexandr Litvinenko.  He was telling the world secrets about the EU which were not in Britain’s interests, in the sense that Blair and Brown wanted us signed into Nice and Lisbon.  Litvinenko was telling the wold that the Head of the EU Commission Romano Prodi was an agent of the FSB.  Russians were imagining that if this became known, Britain might not be so keen to be buried inside the EU.  Unfortunately due to media control being tighter than was imagined, no one anywhere heard what Litvinenko was revealing, unless they happened to follow Gerard Batten MEP on youtube.

It would not be in Russia’s interests to poison its former agents in the UK, when they are still acting in Russian interests, as was Litvinenko.  Undermining the EU is the equivalent of undermining NATO,  the aggressor against Russia.

In Skripal’s case, had be found out secret British war plans against Russia and decided to reveal them?  Something pretty major must be involved here, but what?  The only thing you can be quite sure of is that it was not Putin ordering his liquidation.  The whole of the media is barking up the wrong tree, just as it did with Litvinenko.
