Ukraine's comedian-turned-President has trolled his fellow world leaders with a hilarious spoof video that imagines what their WhatsApp group might look like.

Volodymyr Zelensky, who once played a hapless President on TV but was elected to the real-life presidency in April, put on the mock presentation for guests at a summit in Yalta earlier this month.

The video pokes fun at a a range of global issues including Russia's annexation of Crimea and North Korea's nuclear ambitions, prompting uproarious laughter from the crowd.

It was shared by Indian police officer Rema Rajeshwari, who had friends at the conference in Ukraine.

At the start of the imaginary WhatsApp chat, entitled World Leaders Group, Zelensky introduces himself to his colleagues and is met with greetings in various languages.

Britain's initial response is unintelligible, prompting bafflement from its European allies - perhaps an allusion to Brexit.

A UK message is eventually provided by Prince Harry, who says 'Grandmother [meaning the Queen] wanted me to write that she is very happy to see everyone'.

America, Russia and China then squabble over who is the 'administrator of the group' - before Beijing and Moscow are summarily deleted.

Washington says it wants to invest in Ukraine, at which point Zelensky's predecessor, confectionery tycoon Petro Poroshenko, pipes up: 'Better invest in chocolate production'.

Ukraine suggests discussing 'the credit issue', at which point the International Monetary Fund leaves the group.

North Korea joins the group, to the surprise of Ukraine which congratulates the hermit kingdom on its newfound internet access.

However, Pyongyang admits that it 'actually ran over to South Korea for five minutes' to get a connection.

When South Korea pops up with an emoji, the North retaliates with three rocket stickers, symbolising its secretive missile production.

The U.S. replies: 'Great stickers but you don't have to send them to me.'

America then mysteriously writes the message: 'You are such a beautiful lady', but hastily deletes it and says it was sent to the wrong chat.

Asked about 'the annexation issue', meaning Russia's disputed annexation of Crimea in 2014, Moscow responds: 'What do you think if we annex half of Great Britain?'.

France, Germany and America promise sanctions, leading Russia to comment: 'So nobody has anything against it'.

That is a reference to the West's perceived inaction over the Ukraine crisis and the limited effectiveness of sanctions against Moscow.

Discussion then turns to Donald Trump's plans to buy Greenland from Denmark.

The Danes say it is 'not for sale' at which point China suggests: 'We can create a copy and sell it to you 10 times cheaper?'.

Washington also claims that 'Russian hackers cracked my account' but an account labelled 'Russian Hackers' denies this.

Ukraine then suggests that everyone sends a selfie, prompting pictures of Zelensky, Trump and Emmanuel Macron to appear in the chat.

Belarus struggles with the task and can only provide a zoomed-in picture of strongman Alexander Lukashenko's distinctive moustache.

In another running joke, Finland has been 'typing' for much of the chat, and after several minutes finally manages to type out 'Hi' - seemingly a reference to what is seen as a complex language.

Rajeshwari, who shared the video, said Zelensky had given a formal presentation in the morning and then provided the comedy video during dinner that evening.

It was also shared by journalist Christopher Miller who was at the conference earlier this month.

The video was apparently put together by Studio Kvartal-95, the production company where Zelensky worked as a comedian.

He was elected President in April, thrashing previous incumbent Poroshenko in the second round.
