Involved or delivered the death blow (probably via poisoned snacks or medicine), mostly likely. Appears to have been promised some "fame and fortune" in the event that her husband passed away. Clearly a puppet of someone, imo.

Updated 7:54 PM EST, Fri February 16, 2024; "Jailed Russian opposition figure Alexey Navalny dies, prison service says": https://edition.cnn.com/2024/02/16/europe/alexey-navalny-dead-russia-prison-intl/index.html

The Russian prison service on Friday said Navalny “felt unwell after a walk” and “almost immediately” lost consciousness. It said it was investigating his “sudden death.”

Fri 16 Feb 2024 18.48 GMT (7 hrs, 29 min after official time of death); "Yulia Navalnaya takes stage at Munich meeting after news of husband’s death": https://www.theguardian.com/world/2024/feb/16/yulia-navalnaya-munich-security-conference-navalny-putin

Yulia Navalnaya was in Germany for the Munich security conference, which brings together national leaders, foreign ministers and experts, when Russia’s prison service announced that Navalny had died in jail.

As officials at the conference were taking in the news, Navalnaya unexpectedly took to the stage, addressing a crowd of politicians and diplomats just after the US vice-president, Kamala Harris.

Appears to have been pre-scripted, pre-planned, pre-positioned, etc. Clearly part of a narrative being handed out to the MSM ahead of time.

Order one puppet to take out another puppet M.O.? Extra evil points if they are wife and husband?
