A slick video has mysteriously emerged on the Russian internet where former ambassadors, an ex-general and an ex-prime minister line up to accuse Dmitry Medvedev of betraying Russia's interests while he served as president.
It is unclear who could be behind the anonymous but professionally shot film accusing Medvedev of treason over the NATO-led air campaign in Libya, or if the movie has high-level backing.
But its aim is clear - to damage the public standing of a man who served four years as president and now works as prime minister under his mentor President Vladimir Putin.
The film is the second such bid to tarnish Medvedev's reputation in recent months. An equally mysterious documentary accused him of procrastinating over using force against Georgia in the 2008 war.
The new film accuses Medvedev of betraying Russian interests during the NATO-led military campaign in Libya, citing his decision to abstain from the UN Security Council resolution on Libya that essentially authorised military action in 2011.
That abstention was seen as a landmark moment in Russian foreign policy when Moscow for the first time stopped thwarting Western strategy.
But since Putin returned last year to the Kremlin he previously occupied from 2000-2008, Russia reverted to its previous veto-wielding policy of opposing the West, in particular on Syria.
Evgeny Primakov, a veteran former prime minister and foreign intelligence chief, and several former ambassadors to Libya and officials from Russian arms makers lent their voices to the documentary.
The comments, which appear to be interviews especially made for the film, are interspersed with images of a beaming Medvedev contrasted with children apparently wounded in the Libyan conflict.
"Medvedev deserves to be court-marshalled for his refusal to veto the UN Security Council resolution on Libya," said the voiceover grimly.
The over one-hour-long film claimed Russia might have sustained losses in the amount of $US20 billion ($A19.27 billion) because of Medvedev's policies including his decision to join the Western arms embargo on Muammar Gaddafi's Libya.
