In an unusual move Ivanka Trump briefly took her father Donald’s seat at a summit of world leaders on Saturday.
The US president had stepped away for a meeting with the Indonesian leader during the G20 meeting.
Ms Trump is officially employed as advisor to the president, but absences at the G20 are usually covered by high-ranking state officials.
A BBC correspondent at the summit said he could recall no similar precedent for Ms Trump standing in.
Mr Trump returned a short while later to resume his seat between the British prime minister and the Chinese president.
Ms Trump did not seem to make any major contribution to the key session on African migration and health during her father’s absence.
A photograph of her presence tweeted by a Russian attendee sparked widespread criticism on social media.
Some users highlighted that Ms Trump is unelected, or questioned her credentials – as a fashion brand owner – to sit at such a senior diplomatic meeting.
Others lampooned her appearance among the world’s most powerful leaders after her claim in an interview two weeks ago that she tries to “stay out of politics”.
Ms Trump had joined her father for an earlier G20 event on Saturday on women’s entrepreneurship and finance, along with German chancellor Angela Merkel and Christine Lagarde, director of the International Monetary Fund.
All three women had previously appeared together on a panel during the G20 women’s summit in Berlin in April.
At that appearance she defended her father as a “tremendous champion of supporting families and enabling them to thrive”.
