I don't really see why this would have implications for the relationship between UK and Russia. Isn't this part of the spy game? When one defects, one can expect to be killed. I don't believe the UK wouldn't do the same the other way around. Spying gets you killed, eventually, no matter who you work for.

Because if he was poisoned with radioactive stuff, there is a possibility that some of the stuff got into sewage

Wikipedia suggests he ingested ~10 micrograms of polonium. If somehow even most of it reached the sewage, we'll be talking homeopatic quantities at this point. It's very unlikely it would go through water treatment and end up in someone's food in enough quantity to cause harm.

I agree with you, we can estimate the amount of polonium he ingested, but we surely cannot estimate the amount of polonium involved in that operation.
