In an unusual move Ivanka Trump briefly took her father Donald Trump’s seat at a summit of world leaders.
The US president had stepped away for a meeting with the Indonesian leader during the G20 meeting.
Ivanka is an adviser to her father, but a leader's absence is usually covered by high‑ranking officials.
A BBC correspondent at the summit said he could recall no similar precedent.
There has been widespread criticism on social media.
Trump returned a short while later to retake his seat between the British prime minister and the Chinese president.
Ivanka did not seem to make any major contribution to the session on African migration and health during her father's absence.
