Donald Trump was recorded off camera saying "get me out of here" to an aide at the end of the G20 summit in Argentina, as he walked off stage even as other world leaders gathered for a photo.

The US president was also scheduled to pose for the final photos, as the meeting in Buenos Aires came to an end after a whirlwind two days.

But footage shows Mr Trump shaking hands with Mauricio Macri, the Argentinean president, before rapidly walking off stage.

Mr Macri, who stretched out a hand after him, appeared confused by the US leader's behaviour and was left alone in front of the photographers.

An aide then rushed across the stage after Mr Trump who, off camera, can be heard saying "Get me out of here."

Despite the president's wishes he did eventually return to the stage, to pose for group photos with the other world leaders.

The 72-year-old has previously made awkward blunders during photo opportunities with other dignitaries.
