Two Russian pranksters released footage of a video call with British Foreign Secretary David Cameron in which they led him to believe they were former Ukrainian President Petro Poroshenko.

The call appears to have lasted around 15 minutes.

In the video, Cameron is heard talking about discussions he had with US Republican presidential candidate Donald Trump in which he pressed him to allow Republicans to vote in favor of US military aid to Ukraine.

Cameron is heard asserting that Trump believed that a deal could be made with Russian President Vladimir Putin in which Russia would take control of the eastern Donbas region and the Crimean Peninsula. The UK's foreign secretary criticizes the idea as flawed, arguing that Putin would want to take more.

Cameron is also heard saying that Ukraine will not be invited to join the NATO military alliance next year due to US opposition.

Britain's Foreign Office said that the call looked like an operation designed to draw attention away from Russia's invasion of Ukraine. It did not answer a question on the video's authenticity, according to the Reuters news agency.

The office reported that Cameron had been the victim of a hoax video call earlier this month.

The two Russian pranksters, who use the aliases "Vovan and Lexus," have targeted other British political figures in the past, including then-Foreign Secretary Boris Johnson and then-Defense Minister Ben Wallace.

They have also held prank phone calls with Turkish Prime Minister Recep Tayyip Erdogan and Italian Prime Minister Giorgia Meloni, as well as former German chancellor Angela Merkel.

The duo has denied having links to Russia's intelligence services.
