MOSCOW (Sputnik) — Russia regrets that the case overshadows relations between Moscow and London, Foreign Ministry spokeswoman Maria Zakharova said.
"There was no reason to expect that the final report of а politically engaged and highly non-transparent process, with a predetermined result, could be objective and impartial," Zakharova said in a written comment on the report issued earlier in the day.
She added that Russia's position on this issue remained unchanged and well-known.
Following his death, UK authorities claimed that Litvinenko's former colleagues had poisoned him with the radioactive isotope polonium-210. A public inquiry into Litvinenko's death was formally established by the UK government in July 2014.
"We need time to study in detail the content of this document [UK report on Litvinenko's case], and then we will give a detailed assessment," Zakharova added.
