what is the link b/w great britian and russian spy Lutvinko?

Question

i dont understand y great britian is taking so much interest in lutvivinko's death as he was russian.he acused Vladmir putin of ordering slow death to him,y not America get involved in it.

Answer 1

I think it is because this guy lives in Britain now or something. This is where they have found a lot of the poison that he had in his system. It is in some planes in British Airways etc. I think because it effects their home soil. I don't really see why anyone but Russia and Britain should be involved because Britain was where it happened and Russia is who he was working for.
