Litvinenko's own words via the 2006 diary (with the original diarist's emphasis replaced by mine):

"I ordered lunch but he ate nothing. He appeared to be very nervous. He handed me a four-page document which he said he wanted me to read right away. It contained a list of names of people, including FSB officers, who were purported to be connected with the journalist's murder.

"The document was an e-mail but it was not an official document. I couldn't understand why he had to come all the way to London to give it to me. He could have e-mailed it to me."

So Litvinenko spoke about a list of perpetrators, and didn't understand why Scaramella thought it important to show it in person. But here is how the BBC presented the story after Scaramella's twists:

BBC NEWS | Programmes | Panorama | How to poison a spy: Transcript

MARIO SCARAMELLA
Spy Investigator
I received the weeks before November 1st several messages from a source mentioning a growing alarm, a growing risk, and Litvinenko was mentioned several times.

[...]

SWEENEY: In return Scaramella wanted to warn his friend that he'd received a death list with both their names on it.

SCARAMELLA: The email was the reasons why I contacted him.

So now the list became one of targets. One could hypothetise that there have been two lists, but Litvinenko's failure to mention it and his wondering about the point of the meeting contradict that.
