There is no motive whatsoever for Putin to have been concerned with the dead spy, Litvinenko. He was of no consequence or threat to Russia.

Probably, Litvinenko's death was due to the fact that he was engaged in the smuggling of nuclear materials and accidently poisoned himself.

What these unsubstantiated attacks on the President of Russia are doing is elevating Russia. The non Anglo-Zionist world, which is the largest part of humanity, has lost confidence in the veracity of the West. The Western media, a collection of prostitutes, is in such lock-step mindless compliance with the anti-Russian agenda that the most implausible accusations against President Putin are reported as if they were proven fact.

Western news organizations, such as the BBC and the New York Times, once respected news organizations, are now widely regarded as government propaganda organizations that lie for their living.
