Putin's spokesman Dmitry Peskov told journalists the Kremlin would not check out a report by British investigative group Bellingcat that the suspect it identifies as military doctor Alexander Mishkin was made a Hero of Russia, one of the country's highest awards.
"This topic, if you remember, we don't discuss," Peskov said, saying this was "in order not to get drawn into debates with various organisations and media".
Pressed by a BBC journalist on whether the Kremlin would check the claim, Peskov insisted: "No, no, I won't do that. We have no official requests from the British side on this matter. Here we have taken up a certain position, we will stick to it".
The two appeared for an interview on Russian state television after Putin insisted they had not done anything criminal.
Peskov, who has a broad remit to comment on the Kremlin's views, has repeatedly refused to talk about Bellingcat's identification of the suspects.
"Since the whole discussion is being held at the level of media, we, as the Kremlin, don't want to take part in the discussion," Peskov said last week.
"We won't hold a conversation any more with media." Peskov had denied Bellingcat's earlier claim that the other suspect, whom it named as Chepiga, was also a decorated Hero of Russia, after telling journalists he would check lists.
"Yes, we checked. I don't have information that someone of that name was decorated," Peskov said late last month.
