A nasty little nugget, retrieved from the acres of Skripal coverage. when Litvinenko was murdered in London, his dad Walter was in Italy, furious at the Putin regime which had ordered the killing. But years later Walter's back in Russia, sitting on a sofa in a TV studio with Lugovoi, one of the men responsible. they're chatting amiably, and shaking hands, so that the Russian viewers can clearly see that the whole thing was a nasty plot, made up by the West to smear the motherland. (Remind you of any recent coverage?). So what exactly went on to persuade Walter to change his mind? We may never know, but all the guesses are deeply unpleasant. There are no restrictions or limits to get in the way of the main objective - making Putin look good.
