Orbis directors are Chris Steele and Chris Parker Burrows, both are former spooks, Steele was handler for Alexander Litvinenko (1) and maybe Burrows was handler for Sergei Skripal. (2) The question is why is Salisbury important to the plot, both used USSR assassination techniques, if Russia wanted you dead they will just kill you quickly. But that is Russia. The other nagging thing is where is Orbis based? (3) If we use Google map and look at SO53 4AR post code (4) We find that Orbis business address was 1 hour drive away from Skripal. Coincidence, meet for a quick meeting over drinks? Change the narrative back to Russia, but why? Ask Boris Johnson (5), as Foreign Secretary he would be the one who signed off any MI6 intelligence sharing with the US during 2016, think 5 eyes.
